I have sprained my ankle very badly, this happened October 13th. I was on crutches for a week, then a walking boot for 4 weeks, then limping for 2 weeks. About 2 weeks ago I started running and swimming and doing sports again (I'm very active), but on Friday I had fitness class where we did rock wall climbing, and then swim practice which doesn't really affect my ankle because I'm kicking from my hips. It is again very swollen and discolored. I have had x-rays before and the doctor said it was a very bad sprain. But should the pain be back? I wasn't doing anything different just my normal routine.
