I wore one for 4 hours in town today, I know exactly what you mean!!!Try working in a surgical mask for 9 hrs a day, all the while being semi allergic to whatever they are made of. When I mean working, I mean actually exert yourself, then let me know how you feel about wearing them.
I work at the hospital and have no choice in the matter, we are not allowed to wear the homemade ones. My face has bumps some of which I have scratched until they have bled.
I would give anything to be able to wear a soft cotton homemade mask to go shopping in. But I can't and even when I am home and around my husband I have to wear that nasty mask to protect him.
So to all those complaining you can't get surgical masks, Be happy you don't really need them or have to wear them while you work.
