Hi Mark! Good to see you back!
I'm sorry you're still having problems with your foot. I wish I could diagnose for you, but it's just not possible. You'll need to have your doctor look into it. There could be nerve damage, as Otis said. The bones themselves may have become misaligned after surgery. There's so many possibilities.
"See your doctor," may sound cliché, but it really is best.
I have chronic pain from breaking my foot too, but I doubt my issues are the same. I just stopped in to welcome you back, and wish you well.
