Does this sound like a strained chest muscle: For the past 4 weeks Ive had a pressing/pinching pain in one small spot on my chest. It doesn’t hurt more when I press on that spot. It’s on my right side, 2 inches from my sternum, and 5 inches below my collarbone. Pain is a dull gnawing pinch. It stops throbbing when I lay down and it doesn’t hurt immediately upon waking. Usually after about 2 hours of going about my day, I begin to feel it, and it intensifies throughout the day. Cardio exertion (riding an exercise bike) does not make it worse. Taking deep breaths does not hurt. Laughing/coughing/sneezing does not hurt. Aleve and Advil relieves the pain. Ice and heating pad help too. I have no shortness of breath, and no chronic cough or fever. Full blood panel and Dimmer (blood clot test) came back normal/fine. I feel fine besides the terrible fear of this chronic chest pinch. Prior to getting the pain I was quite active - taking workout classes with planks and pushups, tricep dips. I had also been lifting the spa cover at my house without help. Could I have strained a pec muscle? I’m terrified it’s a tumor that’s pressing on a nerve.
