Also, ive been prescribed a gel that apparently will relieve my clavicle and shoulder pain but it doesnt seem to work. doctors told me its from my muscles because my breasts are way too heavy plus i have no problems with my heart bc i already checke?

You probably have strained muscle(s) in the upper chest and the gel could be a NSAID gel (diclofenac) or local anesthetic (lidocaine gel or alike). The gel may not be strong enough. You can try ibuprofen or advil OTC 200 mg, x 2-3 tablets every 6-8 hours with some foods for a couple days if you do not have stomach or kidney problem. Besides NSAID pill, apply warm compress may be helpful.
