Male syrian hamster - red bump on genitalia

[gojohamster]

Hello!

This is my first post here! I’ve just joined as i’m desperate for an answer and have not been able to find it anywhere.

Last night i noticed a red pimple looking bump on my hamsters penis (1yr old syrian).
I check him every day so i know this is new from yesterday.
I clean his cage every day (remove urine and poop), so i’m not sure how this happened.

I was wondering if this was an abscess and what course of action should i take?
Is there a chance it will pop on it’s own? How long should i wait until bringing him to a vet?

I have emailed a few vets asking for the price of draining it (as i suspect it is an abscess).

Any information/advice would be helpful!
He’s been my baby for 1yr now but he’s my first hamster so i’m still new to all this☺️

I’ve attached an image.

Thank you!
