Hello, I dropped something on my big toe joint 4 months ago.

Hello, I dropped something on my big toe joint 4 months ago. My big toe mobility is like more than half as much as the good toe. There is still some residual inflammation and pain. I have done multiple X-rays and an MRI which are almost clean. Nothing interesting could be found on that. When I stand or bear weight my foot turns red/purple but as i walk it becomes normal but the discoloration is still in the leg, but foot become normal. No clots. There is inflamation under the fouth and fifth matatarsal and inner ankle probably due to my comsensatory gait. I started exercises but that gave me pain in outer ankle and outside of the foot. I have been to 2 podiatists and a physiotherapist too. Nothing seems to help. I am at my wits end and don't know how to go about the healing. It's really very difficult to walk or stand for wven 5/10 minutes. Please help.
