Swelling in random places on the foot as well as the big toe sounds like gout to me. I had it a couple of times and the pain was unbearable. Like pins and needles in the various joints in my left foot.
Your hurt.
Your ankle may never heal on it’s own or it may but it won’t if you keep hurting it. You need to not stretch the tendons in your ankle for at least 6 months perhaps as long as a year. One day you will wake up and realize that it no longer hurts if it heals. If you still have this problem in a year you might want to consider alternatives.
Surgery is not always successful and sometimes creates more problems than it solves. The human body is well made, it can’t always repair everything but it comes close.
Good Luck.
