Recent MRI shows "bone bruise" on r) femur with marrow edema. MRI for knee pain. Have had swelling, pain and locking in r) knee. Also, on MRI saw a "cyst" on the ACL. Lateral and Medial miniscal tearing also seen on MRI with "trauma/weakening to the ACL". Recent 6 mo history of hair loss, weakness/fatigue. Also a r) kidney cyst found with elevated BUN. All my googling point to "multiple myeloma". Will be discussing surgery for knee with MD tomorrow.
