Strange lump/boil on top lip..PICS!

[doris2008]

What do you reckon this could be? It started off about a month ago, where the area on near side of top lip went solid. I thought he had been stung, as this happened last year & after a while a ring formed with a central spot which eventually healed (vet did confirm). I have just ignored it as is hasn't changed, doesn't appear to be causing him pain & when you feel inside his mouth there is no sign of anything.
This morning when I went to turn out it had suddenly grown into a boil sort of thing, its kind of hard, but the very centre squishes in as if its about to pop. Again he doesn't seem in pain, let sme poke it & is eating happily.
Could it be that he's poked himself with something & its absessed?! Never seen anything like this before...

Hard to see on this one, but its too the right of his nose as you look at it.

It could be an infected hair folicle from a whisker. He may have pulled the whisker out allowing a little infection inside.

Can you get a warm flannel and rest it on the area? It will help bring any infection to the surface quickly. Then apply sudocream or savlon etc.

It could be a fly bite, but these are generally painful.

I thought it might be the start of a melanoma, but as he had it before and it disappeared, I do not think it is.

I think it is an infected hair folicle.

If no better soon, I would get the vet out to be on the safe side.
