Toe nail trauma, now separating.

dropped a heavy wooden shelf on my big toe a few weeks ago. Toe immediately started getting blood under the nail, swelled up etc. Swelling finally went down, pain is gone, I can bend the toe and move it freely. still has lots of black blood under it and it has started to separate from the cuticle. The part at the edge of my toe still seems firmly attached though and not loose. should I go to a doctor and have it removed since it is only separating at the cuticle Or will it all come off eventually?
