Broken Collarbone still causing problems

I recently am getting back into lifting weights and have become frustrated with myself. I broke my collarbone over 2 years ago and it is still preventing me from working my chest and shoulders properly. I have a huge lump on the outher third of my right collarbone. I had seen two doctors, and they both say the lump will shrink with time, and light weight lifting will help the problem go away.

Well whenever I try to do a chest press or push up, I can feel my bone "popping" in and out of place still, even with 25 lb dumbells.  The popping occurs at about 80% of my extended range and does not hurt that much, but the area feels sore and awkward after lifting weights.

Are their other excercises that I can do that will help build my muscle back, and stop this poping and pain I am experiencing, or am I only hurting myself more  trying to lift weights. I don't like the idea of surgery, but I am considering it if there is no way for me to me "normal" again.

Thanks,
Dan

If you keep experiencing pain on movement then id recommend getting the opion of a good ortho surgeon.
 
While im never keen on surgery wihtout trialing other things first, sounds like this is a problem that might best be fixed with some minor surgery.
 
Get a ortho consult.
