My friend was complaining that a certain area on her breast hurts, but there’s no lump, bruise, or anything like that. She has a doctor’s appointment. The doctor’s office said that it may be a small cyst that she cannot feel. But, my friend keeps saying that it’s a pinched nerve. Can that happen in the breast? I thought a pinched nerve is when someone makes a quick movement and the nerve gets pinched in a joint, like in the neck.
