I Smashed My Shin In Martial Arts Class 2 Weeks

I smashed my shin in Martial Arts class 2 weeks ago Thursday. it took about 7 days until my foot started turning bruised from it. a few days later my ankle is swelling. If this would of happened a few days after the incident i wouldnt of thought anything of it. It just seems odd that it took this long for the swelling and bruising to occur. I just want to make sure nothing else is happening. i have no pain in my foot or ankle, my shin is still tender but getting better. Should I just wait this out or can i do anything to accelerate the healing?
