anesthesia
"Agree with everyone about out like a light and feel great minutes after an upper endoscopy.  Do want to share that I woke up the next morning with charley-horse-like pain in my upper thigh.  Am continuing to have muscle pain in thighs and calves 36 hours later.  Spoke to anesthesiologist and he said it shouldn't be related to the drug.  He told me the name of the drug and drug sites on line do list it as a side effect. I just wanted to make sure I wasn't having blood clots or other life-threatening symptoms.  Hopefully, it will go away soon. Just be aware this can happen and maybe take Aleve or some such for pain."
