hi . 1 month ago i got hives and its been on , on nad off but itz gone now and the sweeling to my right foot is a little tender though. but when my foot was swollen it was difficult to get up so one day i tried to lift my self off the floor using unusual positions and then i got a bad spasm in the back of my right calf and kind of twisted my ankle but not to the point that it got swollen well really i couldnt tell cuz my ankle was swollen from the hives but anyways after the hives went away i started to feel around my foot and legs and it was feelin better only my right foot and ankle and calves were tender to the touch . so then i tried to move my left foot in a upward and backward gentle motion and it was fine. but when i tried to do it with the right foot i couldnt it hurted so bad i couldnt even move it a little up. and itz been 4 weeks with this pain in my ankle left side of my leg close to the ankle. what can it be? should i go to the doctor immediatly?
