Fly larvae living under skin?

[MochaDun]

Is this possible? - I know bot larvae can sometimes bury outwards through the skin. Can other flies lay something in a horse's skin? My pony got bitten I think about 10 days ago - he was very fussed and shaking his head like something had got him one day when we were about to go out riding though I thought he'd hurt his ear. A few days afterwards I noticed some yellow thick discharge from a tiny cm sized lump under his chin over his jaw bone, I trimmed the hair back and it had a small pin prick hole in the middle. I squeezed gently and only a tiny bit more yellow discharge emerged, no smell, a tiny bit swollen around it but nothing significant. I cleaned it all up and put on antibacterial cream as assumed it was an infected fly bite. It seemed to go down a bit over the next few days but I kept applying cream and just kept an eye on it. Tonight another small head on it, which came off as I touched it and again just a small amount of this thick yellow discharge and again this very obvious tiny pin prick hole. Or it could maybe be a small foreign body under the skin but I don't know why the hole would stay open if so? See I'm thinking it's a bot larvae breathing hole... Anyone had something similar?

Our old pony had something similar, sounds disgusting but I ended up squeezing it and out popped a thorn, she was rather keen on blackberry picking and it must have gone right and kept oozing here and there until eventually I squeezed it out.

there are things that look like massive wasps but cant remeber what they are called for the life of me that lay their eggs under skin and are quite serious but rare. Bot larve are rare now with modern worming programmes

I think you are thinking of warble fly larvae rather than bot fly. Warble flies used to be a pest, especially for cattle, but modern wormers (ivermectin) have eradicated the warble fly from the UK. It is more likely that the horse may have been in the hedge and picked up a thorn, that has caused an abscess. My old mare had a similar thing on her nostril, small abscess with a hole. It cleared up on it's own.

the thing that looks like a wasp is a bot fly they lay the yellow eggs that horse lick off and then the larvae grow in the tummy and are pooed out

warbles I think are almost eradicated they are the ones that form a bump and then hatch out.

i don't know what your horse has though.
