anesthesia
"I had a supposedly simple female procedure done in 2007 that was supposed to leave me with a little cramping for two days. The next morning I was in so much pain all over my body. I called the Gynecologist who didn't understand why I would be in so much pain and basically left me to just handle it. I called the hospital to talk to an Anesthesiologist; he got my chart, listened and then put me on hold to look into it more. When he came back he asked, "Does it feel like you have been hit with a baseball bat all over your body?" YES!!! He told me it was a side effect of the medication Succinylcholine. Six months later I was DX with Fibromyalgia! I don't know if it caused the Fibromyalgia but now I feel like I did for that week all the time."
