Getting sick

The past week I was in the ER twice. Once on Monday, once on Thursday. The first time I went there the doctors had no idea what was wrong with me. I had a bad rash on my lower body, Weird bumps on my arms and my muscles hurt everywhere. I could barely walk or move my arms. On Monday the doctors just told me to go home and the symptoms should clear up. Friday my symptoms were a lot worse so i went back to the ER. An older doctor diagnosed me with an autoimmune sickness called HSP. This sickness is really rare in little kids under 5 and the doctor said he has never heard of a case in an older person. Now I am taking steriods so hopefully I will feel better soon.
