I have collarbone pain that gets worse after boxing. it was dull and achy and is now getting sharper. i also have pain in front of my shoulder. please advise?

My impression is that the problem is chronic strain as well as overuse syndrome. Violent repetitive actions of your sport or workout regimen is not what nature intended. I think your entire shoulder region needs a rest from your boxing. If symptoms don't improve, consult a physician or orthopedic sports medicine specialist for evaluation & any appropriate testing.
