It started last year when I was hunting in the snow.. after about 20 mins of walking in knee deep know I had a real sharp pain in my left inner and upper thigh... It took days to go away only to come back after about 5 mins of walking in snow again.. I couldn’t left my foot more than 3 inches off the ground without screaming... I was hunting again a few months ago with friends and it happened again.. didn’t hurt if I dragged my foot along the ground but if I lifted it more than an inch off the ground I would get a sharp pain that started at my knee and shot up my outside and inner thigh...
