What Causes Persistent Large Haematoma Along With Bruise On The Back Of Shin?

Eight days ago I fell against my open dishwasher door and suffered a big gash and large hematoma . It bled some but I have kept it bandaged with nonstick pads and paper tape, just cleaning with soap and water. It is on my lower calf muscle and in the back. It still oozes a small amount of blood and is tender but not severe pain. My hematoma is still quite large and very dark blue. I am concerned about the non-absorption of the bruise. I am in my late eighties and have very thin skin.Should I see my primary care doctor?
