After 2 days of skin rashes and pain around the right shoulder and chest area, I came to see a doctor, and told me that I've got Herpes Zoster

Herpes zoster, also known as shingles or zoster, is a viral infection caused by the same virus that causes chicken pox. Anyone who's had chicken pox can develop herpes zoster. The virus remains dormant or inactive in certain nerve root cells of the body and only when it reactivates does zoster occur. About 20 percent of those people who have had chicken pox will get zoster at some time during their lives. Fortunately, most people will get zoster only once.
So I gotta rest for abt a week at home, because this disease is contagious for ppl who's never had chicken pox.

Has anyone here got shingles before? It bothers me A LOT! It itches badly that I can't sleep last night, and the shingles on the underarm makes moving the arm pretty painful
