Hi Regaarding your experience with the PainShield: As long as there is a damaged nerve or some process that keeps re-injuring the nerve, there cannot be comp complete relief, kind of by definition. In my case, the nerve seems to be damaged by something going on in the hinge of my jaw, for example, that can re-injure the nerve. So, I am careful to not chew on tough meat and that kind of thing. The location of your prior injury to a branch of the TG nerve is unusual, so I don’t have any direct experience to share. However, a fifty percent change in 4 weeks (after you placed the transducer in the right place) is hopeful and perhaps further use will improve things further. If it is not a nerve that is flexed or pinched in day to day use, it is POSSIBLE that the PainShield could help the damage of the myelin covering of the nerve by improving local blood flow, for example. But that is only a guess, since you have an unusual location and source of the injury.
