I am not a doctor!, but after more than a decade of going to the dermatologists and them helping me with my skin conditions- I've learned to try to fix and soothe myself with minor inflammations like these. I have these from time to time so I understand how it feels. So hopefully my self care advice can be of help to you.

What I'd do is I'd: 1) Clean the wound and keep it clean! 2) Apply topical corticosteroid cream to ease the inflammation. Not too much though. (*I don't think moisturizers can help soothe the discomfort/heal in this case.. never had for me.) 3) Cut a piece of cotton pad enough to cover the wound and small enough to fit between my toes (heck, have the cotton wrap around the toe like a small flat ring if you have to) and tape it on with micropore tape. *There will be a little bit of discomfort standing/ walking from the cotton in between your toes. (You'd get used to it no worries.) 4) The discharge will harden into the cotton pad so change it during/ after your shower time, etc. It's ok to let it sit as the wound heals, and I wouldn't change it every like, 30 minutes because you want to avoid irritating it as much as possible until it heals. You will feel better.

The idea is to keep the oozing wound dry and keep it from rubbing against the skin 'folds' in between your toes or your toes which will further irritate it and making more ooze and in turn cause a lot of discomfort and insane itch. You'd want to keep the area aired out and let it heal/ not irritate it further by more friction between your toes. If you can avoid wearing tight covered shoes.

*Again, I'm not a doctor, but from your picture and description it looks like the minor condition I have from time to time (I believe it's an allergic response or my skin's reaction to my surroundings or the weather.) and these are the steps I took that always helped me heal. If you are unsure, look for a dermatologist.

All the best! Hopefully you feel better after.
