I don't like the sounds of that...! Do you get it if you do something strenuous? Have shortness of breath, and break out in a sweat with it? If so, this sounds like heart-pain, otherwise known as angina. If you get it only with eating, I'm not really sure what it could be. Nerves that go to the diaphragm (just below the lungs and on top of the stomach) and have branches that go to the shoulder, and irritation of the left diaphragm will cause left shoulder pain, and maybe left neck pain. If you were a member of my family, I'd want you to see your doctor/PA/NP and get checked out...

The front raise exercise involves lifting weights directly in front of you, targeting the front deltoid muscles. The shoulder press exercise involves pushing weights overhead, targeting multiple shoulder muscles including the front, side, and rear deltoids. Shoulder press is more comprehensive in targeting the shoulder muscles compared to front raise.
