<human>: both of my knees starting hurting, and feels like bruising on the inside across the top of the knees, about 3 weeks ago. now my right hip, right ankle, knuckles of my right hand and my right shoulder are so painful. I can t walk well, and getting off the toilet or putting on a pull-over shirt are all unbearable... what could be the cause?
<bot>: Hello, I understand your concern and would explain that your symptoms could be related to arthritis or a connective tissue disorder. For this reason, I would recommend consulting with your attending physician and performing some tests: - complete blood count, PCR, ESR for inflammation- RF plasma levels-ANA and ANNA antibody tier- calcium and vitamin D plasma levels.  Consulting with a Rheumatologist may be needed. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
