I have Psoriatic Arthritis with only intermittent psoriasis as an adult. Last week I developed a rash with a patch in my finger, side of my heel and on my knee that started off as tiny raised blisters which went down and then left with a pinky red rash which then turned purple which made me to think it was improving and would eventually fade away. A few days later the rash flared up and is now itchy as heck, hot to the touch and has a red ring around it. I know no one can make a diagnosis and I'm not looking for one but I was just wondering if this is autoimmune related or possibly as a result of the DMARD therapy and if anyone has experienced something similar. I take Methotrexate and Sulfasalazine. I have a monitoring blood test tomorrow and will make an appointment. I've tried Eurax cream, kool pak and even Savlon with the lidocaine as it can help with itching. Unfortunately it's keeping me awake at night.
Any suggestions welcome TIA
