Re: Left Shoulder/Arm/Chest discomfort/pain/dull aches ... heart ruled out. Need hel
Do you mean lumps as in sticking out, or something firm under the skin? Are they sore? If they are firm sore spots, try pressing on them very gently, almost to the point of pain but not quite, and hold for about 20 seconds each. They just might shrink down and leave your chest/arm/shoulder feeling a little looser. For more details, look up "trigger points" and "myofascial pain" in your information research of choice.
