I had gamma knife in August 2022. Around April 2023 I noticed minor twitching with my left eye and left side of my mouth. In 2024 I started to have facial spasms near the left eye, left cheek, left side of my mouth, and below the mouth on the left side. It's worse in the morning. Brushing my teeth aggravates it. Tension in my neck and shoulders aggravates it. Too much physical activity makes it worse. I have not been prescribed anything for it. Botox was mentioned if it continues. I've found it helpful to use an icepack on my head and neck. I also noticed the use of a TENS unit has been helpful. If I place the electrode pad on my shoulder it seems to help a lot and it's either relaxing the muscle or affecting the nerve. It seems to help decrease spasms. I have not found anything that helps with the increased head pressure or increased tinnitus.
