I notice a painless throbbing just below my rib cage. I thought it was a muscle tremor, totally pain less. This lasted on and off for 2 weeks. Then I noticed that the tremors stop, and later I felt something iching, I scached it, and felt a little pain, I looked at the area and saw a area about 9 or 10 sq inches bright red, with little pustuals that later turned into scabs. The rash got worse but didn t spread. after about a weak it was healing. Did I get shingles?
