@becsbuddy when volunteering for the Lupus Foundation of America, I learn Lupus and autoimmune disease is rare and mimics other diseases. For this reason, Lupus is not detected until age 29. They're are 5 types of Lupus. If you haven't been tested for Lupus. Ive had lower mobility issues from an injury and Neuropathic Therapy helped a great deal! It is new to medicine. Discovered at Loma Linda. Im not a doctor, but I feel your concern, as I to am navigating through lower mobility. Thank God, they were able to regain blood flow and oxygen back to the nerve. Keep researching. I hope this helps. Bless you.
