If it was ruptured completely wouldn't I have more pain when it's just resting etc? and very little swelling so far. I know, seeking medical advice on a forum, but what can I say lol.
Good question. About 5 years ago I stepped off the backside of the driveway at a friends house. It was dark but I knew the drop was only about 3 or 4 feet so I didn't sweat it. When I looked down I saw the toe of my left shoe catch a big rock and my foot supinated to the point I could see the sole of my shoe.
People asked if I was alright and I told them that I thought I had broken my leg. Someone said they didn't hear it break and I said I didn't either. I grabbed my ankle and my shin and gave it a bend to see if it was loose and nothing moved. That was when I decided nothing was broken. I climbed back up and walked to my wife's car and told her I was ready to go home and get my ankle on ice.
Next morning it was swollen huge and the pain was nearly unbearable and I have a very high tolerance. I read and was told that a high ankle sprain is more painful than a break and I surmised that that was what I had because the pain was unreal at times.
I continued to walk on it and would bend it all around while sitting on the couch to keep it from being stiff when it healed. After a month or so I was able to walk without a limp but still with pain. Another week or so I was able to walk without a limp and without pain but the problem was I couldn't raise myself up on the toes of my left foot. I figured there must be some nerve damage and it was then that I decided to see a doctor.
Told them what happened and my problem and they took some xrays. My ankle, in their words, was "shattered".It was broke in 3 places and the large bone was dislocated a 1/4".
Doctor couldn't understand how I was walking on it. He wanted to re-break it and put screws in it but I said no. He was pissed and told me to at least wear an air cast for the next six weeks. I did that and everything works fine now. No pain, no limp, full mobility.
I said all that to say this. It's probably worse than you think it is but why wonder? You have insurance. Use a little bit of it and find out exactly what you're dealing with and the best way to treat it.
