Saw a foot doctor for the very same problem. Put me on a strong anti-inflammatory for about a month (apparently the nerve in the area gets inflamed and constant impact from activity prevents it from healing on its own) and advised wider/looser shoes with a metatarsal footpad placed beneath the shoe insert just behind the ball of the foot. The metatarsal pads make a huge difference as they take pressure off the irritated area and shift it back. Still use them to this day.

Hoka makes great shoes for this and many are available in wide sizes. Get the pads (Amazon) and give it a try. A bit uncomfortable at first but you quickly get used to them.
