I am 55, slim built, no disease. For a month, I have stated having pain in my knees. it started with left knee and soon having constant pain in both knees. Sometimes I feel pain in different parts, from thigh to calf mussles and I feel a strong urge as to tie some rope at different places for 1 or 2 minute as it gives me temporary relief. While waking up in the morning, I feel low back pain. No arthritis history in our family. I had been an airlines officer with a quite hectic life. After taking voluntary retirement, I am confined to home, though regularly taking 2-3 kms walk daily. I am taking calcium tablets, voveran 50 mg on my own and applying local pain relieving creams. My urine test is normal. Should I go for blood uric acid or any other test. Kindly prescrible some remedy.
