Hi.
I tried both, pt definitely helped strengthen my foot, but made very little difference to the pain. I had 3 cortisone shots in total, 1st 2 worked for a period of 6 wks, then the pain returned, 3rd one had no effect at all.
All that said, I had waited a long time before seeking treatment, and I'm sure things would have worked better had I not delayed. I eventually had to have surgery, but this is definitely a last resort.
Good luck, Mandy.
