Hi I recently had a biopsy as I had a rash on my chest & back for nearly a year, the results came back showing it could be two different conditions. First was lichen planus for which I have been prescribed a steroid cream, the second was I could have lupas but not confirmed. I have to go back to the hospital in a month but since my last visit I have been getting other symptoms, swollen ankles, severe pain in one of my knees, I am now on strong pain killers but if I do not take them regularly the pain is really bad. Now my urine has started to smell strongly of amonia, I,m tired all the time and gaining weight.
