When I bend my fingers , I am feeling stiffness in fingers of both hands. Also there is frequent popping or cracking sound in my fingers, wrists and shoulder joints for last 20 days. I have been tested -ve for Rheumatoid Arthritis.
Now on blood tests, Random Blood
Sugar level is 155 (Normal range 70-140) and
Vitamin B12 serum level 932 (normal range 200-900). Also low level of MCH and MVH but Mean Platelet Volume is higher than normal range.
What does this health condition indicate ?? Why vitamin B12 serum level so high (932) ?? what does test report suggest ?? Please reply.
