My younger brother is having pain problem in his legs. This problem started in January 2018.In January he used to have little pain in his leg joint (that is in patella region). Slowly and slowly it started increasing and unbearable. In may he consulted to a orthopedics. Doctor said to a regular uric acid checkup and told to eat less protein diet. He gave medicine (ETox90, Febucare40, Ma-1, Pantonid40,Orthomac oil MQO. But as my brother stops taking medicines the pain comes again. After taking medicines �two months my brother consulted to another orthopedics (thinking that doctor is not catching problem .he even did the same procedure with some different medicines (�RuTon-A, Defzacort-6 mg, Sollievofor) but no help came. Urologist (my father thought that uric acid has something to do with kidney). Urologist said that go to rheologists. Now my family is tired of this and want to have a doctor who could catch the problem. So which doctor should we consult. Nephrologist,rheologist, or some other? And what's most probably wrong is going with my brother.
