Re: ball of foot swelling?
I had some similar feelings going on, of course this was after having 2 metatarsals broken, on crutches, then surgery for something else, then developed what they call Morton's Neuroma. When you would push between the toes, it would about make me jjump off the table. When they gave me shots of novacaine between the toes (they numbed the nerves) gosh, what a difference! I just had the surgery for the neuromas last Friday and am having to deal with imobility. No walking on it for 4 weeks (but after seeing the two incisions yesterday makes me realize why!) and I'm not allowed up for more than 5 minutes every hour, but hopefully this is the answer and I'll be walking norma again, a year later after the break!
I don't know if this is along the right line for you, but the balls of my foot would swell up - more and more as the day went on. Good luck!
