I have tried to do my part and wear a mask when out in public going to the stores and so forth. I am now going back to work and having to wear a mask longer than 30 mins to an hour. I am not sure if it's the mask or a comb. of stress and the mask. I have talked with several in the building I work with they are having headaches as well. I give a HUGE Shout Out to those who have to go even longer than 6 hours wearing masks. I get it is a need, but I am at a crossroads, keep having migraines (I only get 9 pills a month on insurance. Otherwise it's pay full price!) or other.
