Several very localized, intermitent, deep pains in left leg from groin to foot. lumbar mri clear. emg clear. neuro ruled out sciatica. tired of pain.

Claudication?: Are you diabetic? Compromise of blood flow to an extremity can be a cause. Another possible cause would be peripheral neuropathy. Would see your doctor.

Often the details: are not looked at. I find the MRI can be under read and needs an evaluation by someone who looks at images not just takes the report for face value. Also, could you have a neuorpzthy that is being missed. Either way see a musculoskeletal and spine expert who can help you with this.

A few thots: Have you had a NIVA venous study of leg just to R/O thrombophlebitis? Did the EMG test for problems within the lumbosacral plexus, such as pyriformis syndrome. Was a triple phase bone scan considered as there may be autonomic dysfnctn, such as CRPS? Perhaps if no other answer, get a QSART study. This can be diagnosed, and likely needs further consideration. Maybe additional opinions?
