Hard lump on inside on Nostril

[Luxgood]

I just noticed this evening a hard lump inside nostrils ( upper part usually fleshy and soft to touch). Seems to be tender and painful to touch. Other than this horse seems fine.
I haven’t called vet yet as I only noticed this evening. Has anyone come across this?

If it’s brand new could be a sting/bite?

Yeah one of mine got a big lump up a nostril as a bee stung her. Her face got a bit distended with the swelling after a while. She had some bute and ABs from the vet, it did eventually go down but it must have irritated a nerve as she became a photic headshaker after that.

Hopefully yours will go down of its own accord!

Could be a bite but one of mine had a sarcoid come up in his nostril luckily it went on it's own after about 6 months.

Also there are flies that typically lay eggs in nostrils of deer .. the larvae become incysted in a bump.. so it might be that as have seen a few incidents where flies that typically use deer to host their larvae have done so on a horse..

Interesting because it’s actually both nostrils now.
