I was told I have shingles by my doctor. The rash started on my left side back with no pain or itching on 5-27. On 5-28 I had some sharp pains in my rib cage area & could not sleep. On the 30th no pain or itching. Still NO itching...Today I woke up & now have another patch on my rib cage area on my left side & now both patches itch. Is this really shingles? I have no pain.
