Allodynia happens when things that don’t usually cause pain feel very painful. This extreme sensitivity to touch can happen after brushing your hair or wearing a cotton t-shirt. Many people with allodynia describe their skin as sensitive. The sensation of touch can feel sharp, stinging or burning. Some might compare the pain to a bad sunburn.
Causes
Alcohol Use Disorder: Long-term excessive alcohol intake exerts toxic effects on nerve tissue, destroying sensory fibers.
Ion Channel Overactivity: Swapped or overactive cellular sodium channels cause nerve endings to fire continuously.
Migraine Disorders: Severe attacks temporarily alter brainstem activity, making the face, scalp, or combing hair highly painful.
Surgical Trauma: Nerve fibers cut or bruised during surgical procedures can heal abnormally and generate localized allodynia.
And finally, If pain is interrupting your life, a healthcare provider can diagnose and treat the underlying cause. It might take some time to figure out what’s causing your pain. To get there, you may need to undergo several tests. You might feel nervous about these tests causing more pain than usual. Your provider can help you manage your feelings, the pain itself and the underlying cause of allodynia to help you feel more like yourself again. All informations are gotten from Cleveland clinics.
