I am getting ready to be scheduled for my second CT miler Graham. I had one 15 years ago and at one point after I had been turned back over on my back -after the catheter was in place- my legs started spasming. They bent at the knee and started opening on their own. It felt like my hips were going to snap and they shot me with Demerol to stop it. I can’t find anything on this being a possible side effect. I’m fine with the Myleogram… I’m just scared of this happening again and wondered what it was and what caused it??? Thank you in advance for any help!
