I am female, 65 years, no meds, elevated cholesterol. Was moving snow yesterday, not overly exerting but I am somewhat out of shape, and experienced what I think is muscle (pecs) pain across my chest. I also have a lump like feeling in the middle of my upper chest remaining today. The chest pain runs horizontally just above the top of my beasts. Is not disabling or sharp. I have no fatigue or nausea. My husband died of a heart attack over a year ago so my daughter is concerned. Any insight.
