I have a small area on my chest /neck area that is red like a rash and has two bumps. One broke open and it has been itchy and irritable. I had a shingle vaccine about 6 weeks ago. I did have shingles a year ago after being given an injection for my rheumatoid arthritis on my thigh, groin and hip area WITH chicken pox all over my body. I was very sick for 2 weeks. It zapped me of any energy I had. I was under my doctor s care. So I kind of wonder what s going on. It s on the collar line so I thought I just scratched the irritation and this came out. I haven t had a headache or flu symptoms. Can you help me?
