What causes soreness in upper breast and shoulder?
Patient: Hi, may I answer your health queries right now ?  Please type your query here... I am 61 years old - white female.  I woke up this morning very sore in the upper left breast (chest) and shoulder blade.  I really think I slept wrong because I slept with my left arm up over my head almost all night.  I just want to make sure it is not my heart.  If I take a really deep breath it is sore and when I turn to the right real far, it is sore.  That's why I think it is just a muscle strain or something. Doctor: Dear Mrs,It is just a neuromuscular pain, may be a muscle strain. Don't worry, take Ibuprofen 400 mg. If the pain doesn't disappear after a single dose, then take it three times a day after the meal for 3 days.Take careCome back if you have any further questions
