i often wake up in the middle of a good sleep with my jaws ( i mean right where the bottom meets the bottom) the joint and immediate area burn and tingles but not a good tingle it painful. i have to slap my face and massage that area for relief. sometimes it sends the pain all of it to the other side of my face. i also have four molars that need to be removed because they are all broken up and i am broke. but its not the molars close to these joints of the mandible,like where my wisdom teeth where located its farther back than that. i dunno if its a side effect or not. ive tried reading the side effects of the medications i take but i get confused easily and like the D>C> crew to explain it to me in a way i can understand. good health my friends and thanks for being there for me... john
