You were all very helpful to me and I'm thankful. It was suggested trigger point injections first and if that doesn't work to do Botox injections. I do use a mouth guard, I have had physical therapy and Ultrasound, accupunnture and massage of that area. I still have oppening issues and pain on my face on both sides. I will give the trigger point injections a go. I didn't think of the tens device on the face, that is a good suggestion I will try . I love how everyone here is so nice and helpful. Lorna
