3 days ago my right shoulder hurt today it turned from my shoulder to my elbow it hurts and now between my boobs my chest feels tight/a bit of pain.

Strain?: The cornerstone of treatment is an accurate diagnosis. Unclear what the cause of your symptoms is - have you been lifting or doing heavy physical work? You need an examination.

Muscle Spasm: Muscle spasms in the shoulder muscles can pinch nerves traversing through them causing referred pain. My recommendation would be to take Naproxen twice daily and to have a friend give your shoulder a massage and isolate any musce spasms. If doesn't improve, find a family doctor who does trigger point injections to relieve the palpable spasms.
