In june I had to go to the ER 3 in less than 2 months. the first 2 were for a severe rash that covered my whole body, swelling, bruises, welts and painful joints. they gave me an IV with steroids, pepcid and something else. the second visit was the next day, gave me the same treatment (IV) but did blood tests and urine tests. they found that my white blood count was over 20,000. i took a round of powerful antibiotics and something else, don't remember what it was. 2 weeks later i was back in for extremely painful and swollen joints, before the antibiotics i always felt like my skin was burning up it went away after the antibiotics. now the burning feeling like i have a fever in my hands is back and my skin starts stinging so bad that i have to try scratching where it is. it wakes me and i can't sleep. Please give me some idea what it may be
