I received a pretty bad bruise a month ago. the discoloration is gone now, however, it still hurts pretty badly. when will it stop hurting?

Hematoma: A deep bruise can result in bleeding down in the tissues call a hematoma. A lump and tenderness can persist for weeks-months after the "bruise" goes away. But it usually slowly gets better. If there are persistent concerns, see your doctor.

Have it evaluated.: You may have a more serious underlying injury. Have it evaluated by a professional and get the appropriate treatment.
