From last two years I have pain in my right leg from buttock to ankle. And some time in left leg also. And always have lower back pain. Some time I can't walk properly. But I do exercise. Daily one and half hour. Both cardio and weight lifting. Sometimes I feel pain more. But I do it regularly. Only main problem is pain in my right leg buttock. And I feel my legs. Are weak as compared to my body. And also always have knee pain. On both legs. Pls suggest do I need surgery .or not. Bcs I am confused. Whether it's a sciatica or slipped disc. I can raise my both legs on lying flat on back. Little pain.in right buttock only when I raise my legs.
