That's my diagnostic tool as well. My GO told me to use the rizatriptan as my first medicine, so if that doesn't kill it then I know it's not a migraine.

My chemistry teacher taught me a trick that knocks the pain back for a little bit - cold head and hot hands. Basically, cool my head down with ice wrapped in a small wet towel, while heating my hands up somehow. It's supposed to pull the blood away from your head which lessens the pain.

USB-C and USB 3.1 comms can create a lot of RF noise which could manifest as lag. I saw this on a laptop with an external hard drive, when the backups were running the wifi died.
