I'm experiencing pain in the upper side of my chest, and it feels like it might be related to a bone or muscle because there's some swelling under the skin. My lower neck sometimes aches too. The pain in the swollen area seems to flare up every now and then. What could be causing this, and should I be worried about it?
it might be lymph node enlargement, take tablet zerodol for 2 days , twice in a day
