Hello, my mom who is 56 years of age is having following problems: - severe regular pain in both the knees but excess of it in left knee. - this pain goes from fingers/heels of both the foot to the hip of left side. I am taking no medicine. Previously in the month of september took pregabalin 1 tablet/day for 20 days and results were promising for that period of time. After the discontinuation, again feeling the same problem. Thanks.
