Uric acid and knee pain. To fish (rohu).

1 month back i had severe pain in my right leg big toe. The doctor asked me to get my uric acid level check and upon checking it came to 8.9. The doctor suggested me zycolchin 0.5 mg for 5 days ( 2 per day) and after that febuxostat 40 for a month. After a month, i didn't check my uric acid but again the pain appeared on my left toe. So i got the uric acid checked and it came out to be 8. So i restated the course for febuxostat 40 and in a matter of 2 days , my big toe pain disappeared. But a few days back, i have started to get severe knee pain in the same leg, so i have started to get zycolchin 0.5 mg also. Today is the 2nd day i have taken zycolchin 0.5 mg but the pain is still immense. Diet - i am taking non veg 1 day per week that to fish (rohu).
