I had an upper endo yesterday. Last night I started getting jaw pain right under my jaw bone at Te corner area. At first I thought it was swollen glands but it seemed odd. I wasn't really sick and its not in a spot I've ever had before plus it came on over night. Could it be from the procedure either holding my mouth open or the dr leaning on my in some way. It's pretty sore. And no ibuprophen because of procedure.
