I Fell A Few Weeks Ago On A Hardwood Floor

I fell a few weeks ago on a hardwood floor and my elbow broke my fall. (I have MS so stumbling is common). Nothing hurt and I was relieved I didn't land on my sore hip. I noticed my elbow was bleeding so I cleaned and bandaged it. It's been 4 weeks and it's still not healed. It leaks and runs but isn't bleeding. It doesn't hurt. Should I go see my doctor or is this normal considering I use my elbow to balance more than most.
