Can TENS on Temple Area Affect Botox in Temple Hairline for TMJ?

I received Botox for TMD (TMJ) one in lower jaw and two just past the temple area into the hairline. I am currently using a Fisher Wallace Stimulator (similar to TENS) that places electrodes on the temples for treatment of insomnia. Should I be concerned that electrical stiumlation on the temples, so close to injection site, might affect the effectiveness of Botox?

Botox longevity with TENS

I am not aware of any well-controlled scientific studies that evaluate the passive activity of muscle contraction and its effect of shortening the duration of Botox effectiveness. It is a theory that the muscle activity would shorten the Botox effect but I'm not certain this is proven.

Botox and TENS Stimulator

You are stimulating the muscle but Botox is a neurotoxin that is blocking the stimulation at the end receptor - so, yes, I believe that stimulation will make you metabolize the Botox faster so you would need to get more Botox sooner than 3-4 months.
