Causes
The virus that causes chicken pox in childhood goes into dormancy. After years, it gets triggered again. The triggers may include age, stress, depressed immune system, etc. As the virus gets activated, the patient gets shingles. The affected area pains for a day or two. After that, the blisters begin appearing. Blisters appear on one side of the body in a band-like fashion.
For some days, new blisters keep appearing. They are full of liquid and are very painful. After that, the blisters begin crusting and fall off in two to three weeks. Pain may remain on the affected area even if all the blisters clear. If you get a blister on the nose, you should inform your doctor immediately because your eyes may get affected. It can lead to vision loss.
