What is this

[Beaniecats]

I did 8 mile walk yesterday, all fine, very cold snow and ice
No issues came home few hours later this appeared on big toe but what is it?
Doesn't feel particularly painful and a blister would hurt wouldn't it?
Is it a blood blister?

Just looks like a fluid filled blister to me, they don’t necessarily have to hurt.

Really? I don't usually get them so assumed they were painful 😆

Yes, it's a blister.

I feel thick now 🤣
Thank you
