Shingles Symptoms and Diagnosis
Shingles Symptoms & Diagnosis
If you have had chickenpox, then a shingles outbreak may be in your future. Shingles are caused by the reactivation of the virus that causes chickenpox.
After you recover from chickenpox, the virus lies dormant in your nerve roots. In some people, it stays fixed for the rest of their lives. In others, the virus can be reactivated when the immune system is weakened, possibly by disease, aging, or stress. Why some people get shingles and others do not is not fully understood. Still, most doctors believe the immune system and stress can play a role in shingles outbreaks.
The first symptoms of shingles are often sharp, burning pain, tingling, or numbness in the skin on one side of your body or face. Shingles most commonly appear on the back or upper abdomen and sometimes on the facial area. It can also cause severe itching or aching rather than pain.
Because they tend to follow nerve paths, the blisters are usually found in a line. Frequently, these lines extend from the back or flank to the abdomen, just on one side, but shingles never cross the body's midline. (The word 'shingles' even comes from the Latin word for 'belt' or 'girdle.') The rash may appear on one side of your face – some people may develop painful eye inflammations and infections.
Shingles rarely lead to hospitalizations in patients with typical immune systems, usually clears up in a few weeks, and seldom recurs. However, there are several complications that you should know about:
- Postherpetic Neuralgia (PHN): People with PHN have pain & tingling that lasts for weeks, months or even years after the skin outbreak has healed. Using medicine may help reduce the duration of PHN.
- Infections: Blisters can become infected by bacteria. You should suspect this has happened if the pain and redness suddenly become worse or go away and then return. Antibiotics may be necessary to treat these bacterial infections.
- Scarring: Shingles risk scarring the skin if the blisters become infected with bacteria. Both situations risk getting into the eyes and causing permanent damage.
While the symptoms of shingles are often quite gruesome, recognizing the signs and beginning treatment as quickly as possible is essential to avoid complications.
