Postherpetic Neuralgia is a painful nerve condition that sometimes develops after you have shingles.
If you have endured shingles but the intense pain remains or returns after the rash has cleared up, you are probably experiencing nerve pain from postherpetic neuralgia.
Burning and stinging are the most common descriptions of the pain from postherpetic neuralgia. Sometimes you may feel shock-like sensations (as if electricity is running through your body).
Even a soft touch can flash overwhelming waves of pain to your brain. This is known as allodynia. Some patients report that a sudden temperature change, such as going outside on a cold or hot day, can also trigger waves of pain.
