in December I was working on a job and I must have banged my big toes around alot and I came home and my toes were all inflated and puffy, a few weeks later I dropped something on them and they were bleeding and eventually they got really inflated and the nails came off(a few weeks after that)

Since then I must have banged them so many times and it kills for about 10 seconds whenever I bang them, my toes look all disgusting and deformed on the top,, could I be causing permanent damage? I really dont want to go to a doctor because I dont have health insurance and the last thing I need is to pay hundreds or thousands of dollars in medical bills,, I am trying to do all I can to prevent myself from banging them and hoping it will eventually heal itself, is this something that will eventually heal itself?
