Question
a long time did pass,i dont have any pain breathing now or any painfull lumps, what did you mean by a weakness do you mean even after it heal if i
do some exercise it will move again?

currently i can do pull ups and push ups with no cracking or pain.

since i can feel no lumps with  my ribs or breastbone could a ligament strain have caused the problem there?

thanks again for your time

Answer
I meant that the rib would heal in a misaligned position so that it would be predisposed to misalignment.  If this happened it would show those symptoms.

I'm not really that well versed on ligament strains so I have to recommend that you ask a medical specialist in physiatry or orthopedics that question.
