I have been suffering from multiple joint pain from last 10-12 days pain in neck,hands,elbow,knees.But there is no other symptom like fever or swelling in joints.I got my blood tests done as per physician and all reports came out to be normal except ra factor as 26(normal range<15 as written).I also had anti ccp done just two days before which comes out to be negative i.e 6.My doctor suggested me calcium and vitamin d3 tablets.I am quite worried how long this pain will last?What cud be the possible reason for this joint pain?I am not getting any relief from these medicines.Please advise.
