Why does my bicep still hurt?

[Jake LaMotta]

I went to PT today for my ruptured pec reapir. I've been going for 5 weeks now since my surgery May 9. My bicep whenever I flex it really hard hurts. As a matter a fact the pec itself doesn't hurt that bad. The only thing that does hurt is the bicep. I understand he drilled holes in the bicep bone and had to do some repair and sewing in there, but why does my BICEP hurt? My chest hurting I can understand but my bicep? Not to mention the bicep feels and looks like it is swelled up.

How long until this pain goes away? I'm supposed to stop PT and start light llifting in 5 weeks but I don't see this bicep or any other pain I have getting better by than.
