Why is my toe continuing to swell and be painful 4 months post fracture?

I broke my toe a little over 4 months ago running to the restroom and somehow slammed my foot on the doorframe. I wore an orthopedic shoe for two months with toe taped for about one month. After being released from wearing the ortho shoe 2 months ago, I have experienced continued swelling, at times tremendous pressure and toe turns bright red. This swelling typically happens at the end of the workday and mostly when barefoot around the house. I'm quite concerned that this is taking so long to heal. I went for an x-ray 2 weeks ago and the bone looked broken still to me. The doctor said that it's possible that it's "healed, but can still see fracture on film". That just didn't make sense to me and obviously it's not healed if I'm continuing with these symptomns. I've been iceing in nightly and elevating it as much as possible even while sleeping. I am healthy with no history of diabetes.
