The Short Answer Educational content only. Any suspected concussion warrants medical evaluation. Persistent sensory symptoms after concussion warrant assessment by the appropriate specialist, an audiologist or ENT for hearing and sound symptoms, a neuro-optometrist or ophthalmologist for visual and eye symptoms, and a physician or neurologist to coordinate care. Consult a concussion-experienced clinician for individualized care. Touch sensitivity develops after concussion because the injury sensitizes the pathways that process touch, so ordinary contact is amplified into discomfort or pain (Ashina et al., 2019). Touch signals travel from the skin through the nervous system to the brain, where they are processed and interpreted. After concussion, these pathways and the brain regions that handle them are in a sensitized, hyperexcitable state, so normal touch is amplified and can be perceived as unpleasant or painful. This tactile hypersensitivity is a form of allodynia, pain from a stimulus that should not hurt. It often accompanies headache and the broader sensory sensitization of concussion. Treatment calms the sensitized nervous system, uses graded tactile exposure, and treats coexisting headache rather than avoiding all touch. Concussion sensitizes the pathways that process touch. Ordinary contact is amplified into discomfort or pain, a form of allodynia. Calming the nervous system and graded exposure reduce it. What Touch Sensitivity Is Touch sensitivity, or tactile hypersensitivity, is a heightened and often unpleasant response to ordinary touch. Light contact, clothing against the skin, textures, a hand on the shoulder, or the scalp being touched can feel uncomfortable, irritating, or painful at a level of contact that should be neutral or even pleasant. When a normally harmless touch is perceived as painful, this is called allodynia. Touch sensitivity after concussion can be generalized or focused on particular areas, such as the scalp and head, where it frequently accompanies headache, and it often travels with sensitivity to light, sound, and other sensory input. How Concussion Sensitizes Touch Processing Touch is processed through a chain: receptors in the skin detect contact, nerves carry the signal to the spinal cord and brainstem, and the brain interprets it. After concussion, the nervous system is in a sensitized, hyperexcitable state with reduced inhibition, a condition called central sensitization. In this state, the touch pathways amplify signals, and the brain's threshold for perceiving touch as unpleasant or painful is lowered. Ordinary contact that would normally register as neutral is turned up and can cross into discomfort or pain. This is the same sensitization mechanism behind post-concussion light and sound sensitivity and behind the headache itself, expressed in the tactile system. The scalp tenderness that so often accompanies post-traumatic headache is a familiar example, where the head becomes tender to touch as part of the sensitized pain state. Why It Travels With Headache and Sensory Overload Touch sensitivity rarely occurs alone because it shares its mechanism with the other sensory symptoms of concussion. The same central sensitization that lowers the threshold for touch also amplifies light, sound, and smell, which is why these sensitivities cluster together. Touch sensitivity is especially linked to headache: cutaneous allodynia, tenderness of the skin of the head and beyond, is a well-recognized feature of migraine and post-traumatic headache, reflecting sensitization of the pain pathways. When the nervous system is already overloaded by other sensory input, touch tolerance drops further, so touch sensitivity worsens during sensory overload, fatigue, and headache flares. Symptom Presentation Ordinary touch feeling uncomfortable, irritating, or painful Scalp and head tenderness, often with headache Clothing, textures, and light contact feeling unpleasant Flinching or discomfort with being touched Sensitivity that is generalized or focused on specific areas Worsening with sensory overload, fatigue, and headache Overlap with light, sound, and other sensory sensitivity Assessment A physician or neurologist assesses touch sensitivity by characterizing where and how touch is amplified, its relationship to headache, and its place within the broader sensory picture. The assessment distinguishes central sensitization, in which touch processing is amplified, from nerve injury causing altered sensation in a specific nerve distribution, since these differ, and it identifies coexisting headache and sensory symptoms that share the mechanism. Recognizing touch sensitivity as part of the sensitized post-concussion state guides treatment toward calming the whole system. Treatment Approach Calming the sensitized nervous system is the core strategy. Autonomic regulation through diaphragmatic breathing lowers the arousal that amplifies sensitivity, and treating coexisting headache reduces the shared sensitization, since touch sensitivity and headache rise and fall together. Protecting sleep raises tolerance, because fatigue lowers it. Reducing overall sensory overload keeps the system from being pushed past its threshold. Graded tactile exposure retrains tolerance rather than avoiding touch entirely. Gradual, tolerable exposure to textures and contact, staying within a comfortable range and widening it as tolerance grows, teaches the system to accept normal touch again, whereas complete avoidance narrows tolerance. Choosing comfortable clothing and reducing the most provocative textures helps in the meantime without resorting to total avoidance. As the brain recovers and the central sensitization settles, touch sensitivity generally eases, and treating the whole sensitized system works better than targeting touch alone. Sensory symptoms after concussion improve faster when the nervous system is regulated and the neck and autonomic system are addressed alongside specialist care.

Common Mistakes Avoiding all touch and texture, which narrows tolerance further Treating touch sensitivity in isolation from headache and other sensory symptoms Overlooking central sensitization as the shared mechanism Leaving sleep and autonomic dysregulation unaddressed Mistaking generalized sensitization for a specific nerve injury without assessment Progression Assessment characterizes the touch sensitivity and its links to headache and other sensory symptoms. Treatment calms the sensitized nervous system with autonomic regulation, headache treatment, and sleep support, and uses graded tactile exposure to rebuild tolerance. Touch sensitivity generally eases as the central sensitization settles over weeks to months, with whole-system treatment outperforming targeting touch alone. Why does ordinary touch hurt after a concussion? Concussion leaves the nervous system in a sensitized, hyperexcitable state with reduced inhibition, so the touch pathways amplify signals and the brain's threshold for perceiving touch as painful is lowered. Ordinary contact that should register as neutral is turned up into discomfort or pain, a phenomenon called allodynia. What is tactile allodynia? Tactile allodynia is pain or discomfort from a touch that should not hurt, such as light contact, clothing, or the scalp being touched. After concussion it reflects central sensitization of the pain and touch pathways, the same mechanism behind the scalp tenderness that accompanies post-traumatic headache. Why does my touch sensitivity come with headache? Touch sensitivity and headache share the mechanism of central sensitization. Cutaneous allodynia, tenderness of the skin of the head and beyond, is a recognized feature of migraine and post-traumatic headache. The two rise and fall together, so touch sensitivity worsens during headache flares and improves as the headache is treated. Should I avoid touch and textures to manage the sensitivity? Not entirely. Complete avoidance narrows tolerance over time, deepening the sensitivity. Graded tactile exposure, staying within a comfortable range and gradually widening it, retrains the system to accept normal touch. Choosing comfortable clothing and reducing the worst textures helps in the meantime without resorting to total avoidance. Will touch sensitivity go away after a concussion? Generally it eases as the brain recovers and the central sensitization settles, especially with autonomic regulation, headache treatment, protected sleep, and graded tactile exposure. Because it shares its mechanism with other sensory symptoms, calming the whole sensitized system speeds recovery. Persistent touch sensitivity warrants medical assessment. Why Sensory Symptoms Happen After Concussion Sensory symptoms after concussion arise from disrupted sensory processing rather than damage to the sense organs alone. Concussion strains the connections between brain regions, alters the balance of excitation and inhibition, and leaves the nervous system in a sensitized, hyperexcitable state (Silverberg et al., 2020). In this state the brain turns up the gain on incoming signals, so ordinary light, sound, smell, taste, and touch are amplified, distorted, or perceived as threatening. Some symptoms also reflect direct injury to sensory nerves. Most sensory symptoms improve over weeks to months as the brain recovers and the gain settles, and structured management speeds the process. Graded Exposure and Avoiding Overprotection A common trap in sensory recovery is total avoidance. Completely shielding from light, sound, touch, or activity feels protective, but sustained avoidance makes the nervous system more sensitive over time, narrowing tolerance further. The better approach is graded exposure: staying within a tolerable range while gradually and deliberately increasing exposure as tolerance grows, never pushing far past the point where symptoms flare. This retrains the nervous system to accept normal sensory input. Extreme protection, such as constant dark glasses indoors or avoiding all textured clothing, tends to worsen sensitivity and is used sparingly and strategically rather than continuously. Managing Sensory Overload Reduce competing sensory input by handling one channel at a time Take planned breaks in a calm, low-stimulation environment before overload builds Use diaphragmatic breathing to lower the arousal that amplifies sensitivity Pace demanding sensory environments rather than avoiding them entirely Protect sleep, since fatigue lowers sensory tolerance Treat coexisting headache, since pain and sensory sensitivity feed each other When to Seek Specialist Assessment Persistent or worsening sensory symptoms, symptoms that interfere with work or daily life, and any symptom with concerning features warrant specialist assessment. Visual and pattern symptoms are evaluated by a neuro-optometrist or ophthalmologist. Hearing and sound symptoms are evaluated by an audiologist or ENT. Smell symptoms are evaluated by an ENT. Touch, temperature, and pain sensitivity are evaluated by a physician or neurologist, who can also coordinate care and exclude other causes. New neurological symptoms, sudden sensory loss, and rapidly worsening symptoms need prompt evaluation rather than watchful waiting. The Autonomic and Cervical Contribution Sensory symptoms rarely stand alone after concussion. Autonomic dysregulation keeps the nervous system in a heightened, sympathetic-dominant state that amplifies sensitivity, and cervical dysfunction feeds headache, dizziness, and sensory strain through shared brainstem pathways. Regulating the autonomic nervous system with diaphragmatic breathing and graded activity, and addressing the neck with mobility and manual therapy, lower the background arousal on which sensory symptoms ride. This is why calming the nervous system as a whole often eases sensory symptoms that specialist treatment alone does not fully resolve. References Ashina, H., et al. (2019).
