I found a lump/cyst in my armpit. It hurt the first day I noticed it, but has no pain since then. Now I have many more lumps/cysts. I'm *SLE* 28y/o F?

Get checked. You may have inflamed axillary (armpit) lymph nodes. Are you taking any immunosuppressive therapy, like methotrexate, prednisone or biologics (like rituximab)? These common therapies for systemic lupus erythematosis (SLE) can increase your risk for infection, which in turn can inflame the local lymph nodes. Do see your specialist for assessment. Hope that helps.
