Mortons neuroma and broken tib fib?

Many years ago I broke my leg and had a tib fib fracture. They told me I would be in a cast for 6 weeks but it wound up being 6 months. The leg was never set properly so there was a gap in between the bone that had to fill in. I now have a bump on the bone of that leg. That in itself does not bother me. What bothers me is that since then I have had nothing but foot problems. I have had to have 3 morton neuroma surgeries and one bunion surgery and a bone removal due to a very painful callous. There is tremendous swelling in that foot along with major scar tissue. There is much pain on the bottom on my foot and walking at any length is almost impossible due to pain, Does anyone have any suggestions? When my leg was set it was back in 1991 and then they did not do surgery to set the leg. They set it in the office with my mom pushing down on my leg while the Dr. pulled and I screamed.
