You're priceless! Got a feeling my missus would put the heat patch over my nose and mouth if she ever found out what caused the soreness. She'll find out one day I expect, so watch this space for when I ask for advice on how to breathe out of my backside!
Seriously tho, if andyebs is right about it only hurting a few times then I'll be fine. tbh you can't even call it pain.
