I have intermittent leg pain, knawing type pain, feels as though it s muscular, occurs laterally along the calf and laterally along the thigh...affects ability to walk....I have hx of herniated discs....surgery not an option...feel best when weight is down andI exercise. Back has also been acting up lately. This leg pain affects my sleep. I take 1300mg Tylenol with 2 Aleve but nothing relieves the feeling. Could this be a vascular problem in my legs or more related to my hx of discs (L4, 5, S 1) Thanks. Lynne
