I'm 83 y/o and had severe shingles about two years ago (still have residual nerve pain) and was diagnosed with MG about three years ago. I live in north central Arizona and our recent weather has beaten all past records.

What I'm finding is that I can only spend a very brief time outside before I become very fatigued - especially my arms - and my skin starts to sting like little pin pricks, mostly in my back area.

I do find relief when I come indoors to cooled air, plus sometimes I'll take an Advil or two - for the arm pain. Just some things I've noticed.
