Pain in the joints

[Mumun]

I'm having pain in the left knee for the past few months which has now spread to other joints like the ankle, right knee, wrist, fingers, hip etc. I've been to an orthopaedic.  Knee x-ray shows arthritis.  Blood test results for uric acid was 6.9. Doc gave me meds. After 1 month repeat test showed uric acid as 3.5. But pain in the joints have worsened. Doctor told me to get blood reports for serum calcium,  vit d & anti ccp. Tsh too. Reports were - Ca 9.0, TSH - 1.13, ANTI CCP Negative, vit D - 32. Now doctor has suggested to visit a rhematologist. Pain is not lessened. Pl help!!!
