I tripped and fell over a hard low square box..upon falling, the edge 'cut' into my skin. There was little scraped skin, a slight bruise which disappeared after a week. After a few days of rest and ice it felt better. That was over 3 weeks ago. About 2 weeks ago, a hard lump appeared with pain and it has not gotten better. It is about 3 inches, an egg-shaped bump over my shin. Ice now does not make it feel better. I am walking about all this time of over 2 plus weeks, even with the pain. Elevation of leg when not walking does not help. The pain is constant, day and night . Should I try to see a doctor...a specialist...get a ultrasound...? Please advise....thanks!
