Foot Massage With Tennis Ball

My foot hurts! What should I do?
The bottom middle of my foot hurts (arch). Pain medicine like tylenol stuff w/e don’t help. I soaked my feet in warm water with salts. That didn’t work either. I’ve massaged my foot for hours, with the hands and even rolling on a tennis ball (which helps the most, but only for a few seconds. I wear converse a lot which doesn’t have the best arch support, but the reason I fon’t think it’s that is cuz i’ve been wearing them for a LONG time like a year and have had no trouble and my other foot doesn’t hurt.
also any ideas on what may have caused this would be helpful so i know how to prevent it in the future
Did you go to the doctor? If u didn’t u should go cuz they tell you wats wrong and wut u can do to make it better. That happened to me before i went to the doctor and they told me to not do anything with my foot( no running, exercise, sports, etc.) After 2-3 weeks it wuz better. I don’t know how long the pain will go away, it depends on how much your foot hurts.
