[|Human|] For the last several days I have had severe lower back pain, right side, and yesterday afternoon and still have itchy swollen hands and feet.  Most of my body is itchy as well.  In the past typically I get the back pain in my lower left side but this is a first for the itchy swelling.  What should I do?
[|AI|]  Hi, thank you for posting. I have gone through your query and I understand your concerns. I think that all of your symptoms are caused by rheumatoid arthritis. Rheumatoid arthritis is a chronic, systemic inflammatory disorder that primarily affects joints. To confirm the diagnosis you need a back X-ray, rheumatoid factor test, complete blood count and a urine test. You should take non-steroidal anti-inflammatory disease, in order to treat that kind of arthritis. Ask me for anything unclear. Regards.
