Hi...I had a radical hysterectomy Dec 1/17, started walking again after a few weeks, but with weight gain after surgery and chemo (eating whatever I could get in), I decided to up my game and joined Planet Fitness. It has been going well, using the weight machines carefully, not too much weight on them. Yesterday, I used the ab machine which is like doing upright crunches. When I went to do the next machine, I got a nasty pain in my lower right side that was just weird feeling. It went away after a few seconds but I stopped for the day. Surely after this many months, there shouldn't be any reason I can't workout at full capacity, I would be completely healed inside, wouldn't I? I hope I did not cause a hernia. ?? Anyone else have issues like that 9 months post surgery?
