Try soaking in chamomile tea, or if you are using teabags, you can just wrap it on the affected spot. Chamomile has strong antibacterial/antifungal properties, I’ve taken care of eye and other infections with chamomile, if they are not to advanced of course. Try this and if it doesn’t get better in a day or two, or if it starts getting worse, then have it checked out.
I had all kinds of weird stuff during treatment so far. I had mouth sores, sore throat, popped out or sore glands. Mostly they go away in a day or two.
