Hello,
As you have pain while walking underneath the toe, have you ever taken an x-ray. because I feel X-ray should be the best choice to look upon the bone segments and joints for any signs of
joint inflammation.
Also, how is your footwear? Is it flexible or hard? If the hard switch to flexible ones. Now as you complain pain is only while walking I think your muscles of the feet are weaker now as it's a long time.
Strengthening those muscles is of utmost importance now because if left untreated than may land into other joint troubles for this, dip the feet in hot water fermentation and along with this, add some marbles to it.
Post which you should try taking the marbles out of the water with the help of toes. Use acupressure mat and stand over it. It will be painful but will stimulate the muscles of the foot to start activating.
In my clinical practice of 12 years, we have advised people facing similar pain the above recommend exercise. Most of them have good outcome score.
Hope I have answered your query. Let me know if I can assist you further.
Take care

Jay Indravadan Patel, Physical Therapist or Physiotherapist
