I Had Trauma To My Left Breast When I Opened

I had trauma to my left breast when i opened a door, on December 8th, to our storage unit and several boxes fell on the breast. i was seen by my GYN's associate, who examined me and told me the pain could last a long time.
A week later, i coincidentally had my annual GYN appointment, saw my doctor who examined me and felt the same as his associate.
the pain is making me cranky and i feel a bit flu like. I have been taking Motrin and a heating pad which help temporarily. The pain is getting slightly better but i am still in pain. Can you suggest something i can ask for to take or somethting i can buy over the counter.
