I still have facial pain but not to the degree that I have felt the need to use the Pain Shield. I don’t know if my long term use of the Pain Shield is responsible for my relief, or other factors.
For example, I have always had an uneven bite due to the placement of my upper and lower molars at the very back of my jaw. This causes, in effect, a slight delay in the closing of one side of my jaw and a tendency for the jaw to slide slightly to one side. This, in turn, causes the muscles or cartilage (not sure) just under my cheekbones to to protrude unevenly when I feel them as I bite down.
I brought this to the attention of my dentist, and he made an insert that I wear at night or when I am not talking. It is very thin, but strong, and sort of “snaps” onto my upper teeth. The right side at the back he made thicker, so it compensates for the uneven bite.
You might ask your hubby (a) if his facial pain is present just under the cheekbone, and if he has any tendency for one side of his jaw to be “later” to close. This may be something unique to me, but I have always been suspicious that a lot of so-called TN is really emanating from the jaw hinge, and not way back in the brain as they seem to claim.
Since this area is the same place where I applied the Pain Shield, I do not know which has provided me with the current relief that I enjoy. All I can tell you is that my pain used to be completely disabling for speech, eating, and sometimes even so frequent that I could not sleep.
Right now (knock wood), I would say that my pain is at a 1 or 2 on a scale of 10, and I just have it a couple of times a day for brief periods..
