I was looking for information anywhere on possible symptoms for a reoccurring rash on my back that looks like a purple bruise, periodically covering the top half of my back, on each side. I can't think of any other related sytemptoms however and can't find much online
Thank you for replying however, I don't have a fever I do get night sweats and the rash is looks like a yellowish black bruise. Again thanks for the input
Hi
Have a look at stills disease. That causes a rash in the trunk area, a low grade fever and arthritis. Adult onset stills is very rare. My one friend has it and was in the hospital for a month because they couldn't find a diagnosis.
Here is the symptoms of stills from the mayo clinic website
Symptoms
Most people with Adult Still's disease experience a combination of the following signs and symptoms:
* Fever. You may experience a daily fever of at least 102 F for a week or longer. The fever usually peaks in the late afternoon or early evening. Between episodes, your temperature will likely return to normal.
* Rash. A salmon-pink bumpy or flat rash may come and go with the fever. The rash usually appears on your trunk, arms or legs. Physical contact such as rubbing your skin or exposing it to hot water may provoke the rash to appear.
* Achy and swollen joints. You may find that your joints — especially your knees, wrists, ankles and elbows — are stiff, painful and inflamed. Usually, the joint discomfort lasts at least two weeks.
* Muscle pain. Muscular pain associated with Adult Still's disease usually ebbs and flows with the fever. It may be severe enough to disrupt your daily activities.

Good luck!
