During exercise i got sharp pain under my ribcage (r/s) just below my breast & inner side of my right knee. pain is not shooting (through whole leg + abdomen) but hurts at 2 different points simultaneously when bending over or bearing weight on knee?

I don't think using this forum is the best way to be sure what is going on, you need an in-person examination. My guess is that your brain is connecting the pains when there is only a problem in the knee, I am not sure. Does the chest hurt to touch? Muscle, joint and ligament problems require an in-person examination which I wish I can reach out and do via the internet but I can't.
