<s>[INST] Last night I noticed a small rash on my neck.  It was like 3 little bumps.  I did not pay much attention to it, but this morning, I have a rash on the side of my face at my neck line.  It burned like fire.  I went to the pharmacy, and talked with one of them, and she recommended cortisone creme. That helped some with the burning. It looks weird.  I am wondering if I am getting shingles. I showed it to my son tonight, and he told me that his dad has shingles currently. I know my immune system is weak from a hysterectomy followed by bowel resection surgery and I have sarcoidosis (in remission). [/INST] Hi there. I note with interest that you seem to be on the right track at least where diagnosis goes. The pharmacist was right in prescribing the cortisone as that would be my first reaction to assuming it was an irritant reaction or an insect bite reaction. However, if the progress is as suggested & you have never got herpes zoster earlier & your immunity is compromised as you suggest, then it is more than likely your hunch is right & you ail from herpes zoster. Please go to the ER immediately & they will start you on the antivirals required as this is most effective the earlier one starts it. If pas the period of 48-72 hrs, then topical creams will suffice & symptoms are to be treated. Wish you a speedy recovery & Good Luck. Chat Doctor.  </s>
