I had an endoscopy 2 days ago.  The next day I noticed a slight soreness under my left jaw.  Since that is the side I laid on during the endoscopy, I thought that might be the reason.  Today, it is a little more sore than yesterday, but still not painful.  Should I be concerned?
Hi. Welcome to Chat Doctor. I read your query. During endoscopy they at times put bite blocks in your mouth to prevent mouth closure or batting on tube. This leads to jaw pain. Although it's a short term effect. It will disappear soon. A Tylenol or Ibuprofen helps if required. You can do some mouth opening and closing exercise 3-4 times a day to relax your muscles. Avoid stress. Take good diet and HY Chat Doctor. If the pain persists more than a week or worsens, I suggest you see a physician for check up. Hope the answer helps. Thank you!
