<s>[INST] Since March 2012 I have had pains in my left leg. It began just below my left knee. Then my left inner thigh began to spasm off and on until it was always there. Then I began to feel pins and needles in my left foot from the ankle to the toes. Now I am always in pain somewhere in my leg. It never goes away. [/INST] Hithank-you for providing the brief history of you. As you are facing the symptoms which I feel should be connected to the pinching of the nerve root in the lumbar spine. Undergoing an MRI is the lumbar spine will help assist with the soft tissue status.I'll recommend you to undergo physical therapy like - Therapeutic ultrasound therapy and TENS therapy for reduction in pain. Also exercises like core stability, spine Strengthening, pelvic floor Strengthening and lower limbs Strengthening should give you better results.in my clinical practice such cases are diagnosed mostly with pinched nerve and respond well to physical therapy regards Jay In Chat Doctor.  </s>
