Apply ice(top and bottom of forefoot like sandwich) for 30 minutes several times a day, 2-3x at the end of the day. Take 2 OTC Alleve tablets twice a day, 2 with breakfast and 2 with dinner, every day(**Assuming you don't have any medical contraindications to it). Get gel insoles focusing on a thick ball of foot area. They also make gel pads for just the balls of the feet. Wear them in all of your shoes. ALWAYS wear something on your feet. Running sneakers when outside and inside if possible. Crocs are great to wear in the house. No barefoot, socks only, slippers, sandals, flip flops. Make sure your shoes fit properly, especially not too narrow. Limit your non-essential activities. You can also massage the ball of the foot and do some stretching exercises. You really have to do ALL of the above things consistently. A little bit here and there is not as effective. They are additive. A month is reasonable before the next step which is a cortisone injection.
