Re: Pain after Cortisone shot
I also had increased pain after my cortisone injection into my subtalar joint, but mine only lasted 10 days. My dr was very surprised to hear it lasted that long.
If I were you, I would definitely contact my dr and let him know you have had an increase in pain, it has lasted 21 days, and it is radiating. Communication is key when it comes to something like this.
Keep us posted!
