Have several lumps on my wrists under the skin about pea sized. They are slightly itchy as well as my palms and some swelling on left wrist. Been using Benlysta autoinjectors for 6 months. Could these lumps be a side effect? Its causing some tingling in my fingers and pain shooting up my arm to shoulder. Figure the lumps or swelling are pressing on some nerves. Any ideas or anyone else get lumps with Benlysta?
