I developed an acute sharp pain in my lower back aggravated by breathing last night. Could only breathe shallow breathes in order to limit pain. Pain radiates from lower - mid right back of rib cage to lower right abdomen. Pain kept me awake a lot last night. Is easing a lot today but still hurts with deep breath or sneeze . Have had an upper respiratory bug earlier this week. Also pain is diminished some after a few bowel movements this morning. I have renal cysts , liver hemangioma , ovarian fibroids -all said to be benign. Am in diagnostic process w rheumatologist exploring possible connective tissue or lupus like disorder . Have intermittent edema in lower legs feet hands, sometimes abdomen and sometimes face. Not taking any meds except tried QVAR for a few days but developed sore throat, hoarseness ear pain and what felt like a mild chest infection w low fever so discOntinued it. Cannot take ibuprofen due to swelling. Legs ache and feel stiff sometimes and need elevating. Developed raised veins in hands and ankles and feet in last few months. Rheumatologist says there s blood vessel inflammation. Also says I have angioedema - Im unsure about this. Arthritis seems like two types- osteo( confirmed w X-ray and MRI) and possibly inflammatory as well.
