Dear Sir, I am 60 years old, a retired police officer with a well built body. My body weight is 110KG. I am now going for a walk of 3 KM in the morning and 3 KM in the evening. My grievance is that for the past one day I suffuring from an acute pain surrounding my right knee, The pai becomes unbearable, while folding my right leg, while standing and walking. Previously, I had uric acid problems as a result of which I had pain in my ankle area. The local ortho doctor prescribed ZYLORIC and FEBUTAG tablets. I took it regularly for 6 months. Thereafter, the pain automatically got reduced. Hence, I discontinued those tablets. Now, I have unbearable pain surrounding my right knee. But, there is no swelling or redness around the pained area.
