Was on Protinex supplement and chest grew bigger. Doctor now giving me medication to dissolve far. Advice?

I m facing problem with chest. I ws on protinex supplement frm this August 2013, I hv taken 4 boxes of 400gm each till Nov. I stopped it in Nov bcz I found that my lower chest has grown bigger. In Dec I hv started to feel little pain on my both sides of chest. I hv consulted to a doctor, he told me that it is a reaction of that high protein content(protinex) and run me on some test like C.B.C My reports r normal...nw he is giving me some medicines to dissolve that extra fat...suggestions plz
