I had them in both my feet, first right had surgury, doc did a good job.2 years later had left done doc didn't do a good job , now 2 years later they are back in both of my feet, left is worse. I was never told they would grow back until after second surgury. I had a cortizone shot in the left foot at a doc's office, very painfull and the cysts didn't shrink. then I went to a pain specialist, they put me partial out and gave me 3 cortizone shots in each foot, they shrunk the cysts, but I now get muscle spasms in my feet, but I can aleast stand on my feet.
