Hi I Have been working out on and off for the past year or so. I have had a descent sized lump that seems to be just above my peck muscle. It seems to be apart of the muscle but just pertruding out. I have had this lump for several years and i thought that it was just me going through puberty and i thought that if i worked out it would just work its way out. It hasnt grown or shrunk in anyway but it can be very painfull at some points. Im kinda in a tight spot, should i go to the doctor and have it looked at or just wait and see what happens???
