Last week I got some itch under my left breast, last few days it developed into some kind of rash it's an itchy rash and pricky kind of pain sensation today I went to the doctor he told me it's shingles. Shingles develop when one immune system is low and when one had chicken pox as a child it somehow will develop to shingles in later part of the life. I hope it will cure soon the doctor put me under very strong anti-biotics for 3 days (5 times a day).
