Leg spasm while running

davidbibby

Since July every time I run for more than 15mins my right leg starts to spasm then locks and I have to stop. It starts as a feeling of tightness around my knee and then it becomes difficult to lift my knee and then the spasms start. A physio thought it was a glute or back problem but no success with treatment or months of stretching. I've had an MRI scan and x-ray of my lower back but both were clear. I have no pain so everyone seems to think it a nerve problem. Physio said last week that it may be a trapped obturator nerve and is discussing that with a sports doctor colleague. Anyone got any thoughts or advice? I did Outlaw Half on 1st June and loved it, so I'm feeling v frustrated. Cheers.
