About 4 years ago I bent my leg all the way back and it hurted for 3 weeks straight.. After that it never hurted again.. On November 11 2015 I was playing basketball and I jumped 10 times and it hurted bad I started limping and walking slowly and it still is hurting can you give me an answer on why all of sudden it's hurting and is anything broken or torn but I can walk fine a little.. P.S I was also walking on it and it didn't hurt just when I move fast it hurt.. And my fibula is swollen if it's just under the kneecap
