I am a 34 year old male. I have sores inside my nose that produce a clear yellowish pus. That have been there for months and will not heal. I also have cracked skin where my earlobe meets my jaw that has been there for months as well. Recently I have developed sores on my scalp that start as small raised bumps and escalate into sores. And yesterday I developed a painful rash under my armpit. I am bipolar and take lamictal and I also have psoriatic arthritis and am on methotrexate and humira. Any idea if these symptoms are connected? I was given antibiotics a few months ago as the sores in my nose were diagnosed as staph infection. Cleared up some but not completely. I have also tried antibiotic ointments with little success. Any advice would be helpful. Thank you.
