My husband got some type of skin infection on his left arm where a nurse would take your blood from. This Thursday will be three weeks and it doesn t seem to be getting better. When he first got it I was afraid it could be shingles since it looked a lot like the pictures I saw on google and he complained about a burning pain, but only had it in this one spot. Then after almost a week of putting hydrocortisone on it I took him to Centra care an emergancy clinic, they didn t tell me anything about his infection, what it was, how he got it, but did prescribe him: Prednisone, cephalexin which he s already finished, and triamcinolone acetonide cream. The cream turned the infection into a black scab which has now fallen off, it looks like new skin is growing, however, it s red, inflamed, and sometimes burns, and some of the blisters that formed before are still there and is a yellow puss color. I have pictures if someone could take a look and help, I don t know if I should take him back to the central care it didn t really seem like they knew a lot I do have an appointment for him on Thursday with a dermatologist that s going to costs us $200 so if I could get some help on here instead i d really appreciate it.
