My sister is 52 yrs old - was diagnosed with ms a few yrs ago,- approx. 320 pounds, about 5 9 -- about a month ago she developed a dry feeling around her nose, and her eyes were itchy. She went to dermo who said she had rosasia , he have her tetracycline and she broke out in hives. It s now about one month later she has a rash mostly on her arms, chest and neck that is still itchy and comes and goes in redness. She has also developed migratory joint pain. The only relief she got was when I took her to the hospital and they gave her fluids with steroids, and Pepcid. she felt fine the next day -- but back to square one the next day. She is tired and exhausted because she is unable to sleep well. I don t know what else to do for her. Any suggestions would be helpful. thanks
