No, we don't all have this problem, theres a good possibility you have incorrect form and you stressed your bone or it is just overworked.
I messed up mine years ago in high school, and I actually had to go see a doctor, it's somewhat similar to tennis elbow, in terms of how you treat it atleast. There are some hard wraps, and you wouldn't be able to lift until it is completely healed. If you think you should see a doctor you should, and don't just keep lifting and thinking it'll go away.
And please, like Nobody said, stop posting the same thing over and over.
