I had a thyroidectomy last Tuesday. All went well, except i had a reaction to the anesthesia - couldn't keep anything down, so they kept me for a day longer than planned. i was released on Thursday. In addition, ever since the surgery, i have had a splitting headache. The nausea passed by Wed. evening, but the headache persists. It moves around from the base of my neck on the back of my head, to the very front of my head. is this common and is it a reaction to the anesthesia? I've take ibuprofen, but it hasn't helped. One of the nurses said it could be due to lack of caffeine in my body (i usually drink a cup of coffee a day, but stopped for the surgery.) But i have begun drinking coffee again (since Thursday AM), and it hasn't helped. Any thoughts would be welcome.
