is this a running thing? (TMI probably)

......a spotty arse!

I'm fairly new to running (September) and do 5k three times a week.

Maybe a coincidence but since I started I've had a series of 4 huge individual spots on my arse.

Never really suffered with spots and have literally only had a handful of spots on my buttocks over my lifetime, until recently.

Is this a chaffing thing? Known running phenomenon?

I tend to wear running tights over cotton granny knickers

Get wicking pants instead - the cotton ones hold the sweat next to your skin
