i play soccer and injured my right ankle badly while blocking a short from an opposition player. I slid in and he pulled the trigger with my ankle on one side of the ball. He kicked the ball from the other side very ferociously. immediately i felt huge pain in my foot and ankle which swelled. X ray was fine but i could not walk on the injured foot for probably a week. within 3 weeks i felt a bit better and started playing again wearing a brace (even though the swelling had not gone and i felt discomfort while accelerating) and the pain started to increase again. I realized my mistake a decided to rest again and played once after 2 weeks twice ( 2 times a month). currently i am resting.. the problem is that when i try to exert more weight on the ankle (eg when trying to stretch the calf musle) i feel some pain on the back side on the right and the left ankles of the right foot. 3 months have passed since the injury and the swelling on the right ankle has not gone entirely. usually i have no problem in running or jogging but the swelling increases after such activities. and also while kicking the ball i fell some pain in the achilles tendon.

what should be done get rid of this troublesome problem
