A friend of mine suffers from this. Initially she was prescribed surgery which she refused. Subsequently she was advised to change her footwear to wider fitting shoes, and prescribed custom orthotics. Someone suggested she changed the stack height of her shoes too, she now wears ultra lone peaks daily, and whilst the problem occasionally still reoccurs (generally when she does two or three long days back-to-back) she has found that really helps.
I chatted with her before writing this, she says when it does reoccur she puts pads under the balls of her feet, ice's the affected area, and takes diclofenac (moderately strong anti-inflammatory).
Good luck!
Edited to add: she just messaged me to tell me that when hiking she now uses poles which changed her Gait. Apparently this helps
