Horrible white blister- what should I do?

[Aaaahhhndrea]

I have a blister on my heel. It's about the size of a 50p, the outer edge is purple and the inside was white. It sort of burst so I peeled it part of it off and it now looks even more disgusting.

It was sore last week but actually feels better now. What can I buy? I am going no where near a HCP with a blister during a pandemic

Bit late now you’ve peeled some off. Just cover it and make sure it stays clean. It will go hard and a bit manky but will heal just fine eventually.

I've got it totally bandaged up now, you'd think I was seriously injured

Bleurgh. Thank you.
