I've been fighting against a headache forming for the past couple of days. Because the muscles in my neck/right shoulder have been super tense and it's been difficult to get them to relax and stayed relaxed. So throughout the day I've been getting little zings of brief headaches that don't stick around long.
Which is semi annoying as I'm trying to function but apparently I'm stressed enough that I can't relax. *exhales* 
Hopefully I can keep a full blown headache from forming. 
Brief ones at least don't last long.
