AN ITCHY BUMPY RASH DEVELOPED ON Y UPPER LEFT ARM. A DAY PRECEDING 5-26-13 I had a temp of 99.4 along with aching and chills I have been under a lot of stress. , also dizziness and ringing in my head. Those symptoms went away but the rash got progressively got worse so 5 days later I went to urgent care where I was told I May have shingles given a topical cream. I did have the shingles vaccine 5 months ago . The rash was oozing and spreading down the arm across chest ad a bit on the other arm I went to my doc the next day was told it was poison ivy and was given prednisone ad another cream for a star infection . After using many products for the ivy the first part of rash began to heal but rash continues to spread on chest and back. Went back to the doctor 2 days ago was given a higher dose of Prednisone and Atarax for the itching which keeps me up at night,it doesn't help. This rash now has no fluid . As I said I'VE been under a lot of stress. Any ideas?
