Having recently returned to full time in person work I’m wearing a mask for 4+ hours a day. By the end of the day I feel headachy, sometimes a bit nauseous, my sinuses are more stuffy, and it’s like my whole body is on edge and wants to scream or totally shut down. I just want to sit with my eyes closed for a half hour. I’ve also been having more blurred vision and tired eyes and some research I did in the past has linked that to fibromyalgia, or at least possibly.I have begun to suspect that some of what I’m feeling is related to masks interacting with fibromyalgia. I have realized I need a mask that ties behind my head because the bands behind my ears are part of the problem. Has anyone else had similar experiences? Any advice?
