Yep meralgia paresthetica - pathetic left thigh - cant do 'owt, big blood vessel acting like a boa constrictor squashing the femural nerve around the groin area - has been known on occassions to correct itself. Doc didnt say what the occassions were likely to be but he had a big grin and said welcome to old age!!!!!! Could have a sort of MRI to tell me I've got it!!! Bloody know that!!!!
