Small itchy blisters appearing on arm turning into sores. (doctor, treat, healing)

[Fults]

14 days ago I went to Darwin in Australia. 8 days ago after going out for a day of fishing I woke up with 2 of these sores (they were a lot smaller originally so I assumed they were just mosquito or sandfly bites)
3 days ago another one appeared on they other side of my arm. That is now 3 sores all around my left elbow. I have been regularly treating them with antiseptic cream throughout the day. This does activate them & tgey are also constantly itchy.
This morning I noticed a small blister nearby that too is extremely itchy. I assume this is how the sores begin?
I returned to Melbourne 5 days ago.
Whilst in Darwin I also played football in hot/humid conditions & slept on a old roll out mattress (that possibly wasn't clean) to give some more insight.

Does anyone have any clue to what this could be &/or how to treat it?

Cheers

I go with this.

If they were blisters caused by rubbing, they wouldn't have taken so long to develop.


And unless you've got another medical condition like diabetes, they should be healing.
