Cause: Migraine Headaches
Migraine headaches are characterized by intense pain. The root cause of these headaches lies in the chemical activity and alterations in nerve signals within the brain. As a result, individuals suffering from migraines can have highly sensitive nerves, to the extent that even the slightest touch can be painful. It is worth noting, however, that not all individuals with migraines experience a condition known as allodynia.
Cause: Postherpetic Neuralgia
Postherpetic neuralgia is a prevalent result of shingles, a viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox. The varicella-zoster virus can cause damage to the nerves, leading to the development of postherpetic neuralgia. One of the potential indications of this condition is an increased sensitivity to touch.
