I checked my uric acid level which is found in normal range. I got tested for rf test which emerged positive and other test like anti ccp and hla b27 test as negative. Esr comes to be 42 mm/hr. I don't know whether these values are true or have error. Not tested for vit d and calcium, thyroid. I have joint pain and muscle weakness symptom for a long time nearly 6-7 months especially in the morning time.
