I am experiencing chest pain sometimes but it goes away, and i sometimes feel like i have to take a really deep breath. i also get pain a lot under my right collarbone, around when i get the chest pain?

If you have chest pain, please see a physician right away. Most likely it is related to muscular strain, but sometimes there are additional conditions such as a cardiac abnormality or fluid around the lung which may be related to your symptoms. Acute or urgent care centers are available and some of the centers have imaging on site. Watch for signs of air hunger, dizziness and feeling faint.
