What causes pain in the lower leg?
Patient: I have had pain in my right leg. Usually it is in the back of my thigh and wraps around my knee down to my ankle. Popping noise when straightening my leg. I did fall over a year ago but the pain has gotten more severe of the last few months. Really hurts to straighten my leg. I do have loer back paid also. Doctor: Hi,  Your symptoms are suggestive of radicular pain in lower limb as result of disc prolapse in lower back. Radicular pain occurs due to nerve root compression in lower lumbar spine and pain is like radiating from knee to ankle and foot as you described.   Diagnosis can be confirmed by MRI of the lumbo sacral spine. MRI is very sensitive and specific for diagnosis of spine pathology. Meanwhile start tablet Pregalin one at bedtime with tablet Ultracet twice a day for pain relief. Visit to spine surgeon for detailed clinical examination is recommended.   Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Jayesh Vaza, Orthopaedic Surgeon
