I have the same issue.
But I never attributed it to my treatments. Maybe I should. I had started noticing it more in the last year. I had thought it to be because of my weight gain. I have gained 18 pounds since surgery. I am trying to watch my diet, but by my own admission I have been my biggest problem there. Have you noticed any issue with the waste line? LOL I mean with the same problem with the elastic lines?
