Nose bleed, sinus infection/mycosis?

[soloequestrian]

Note: I spoke to the vet when it happened and horse is booked in to be scoped, I'm just interested in other experiences.
12 year old had a random nose bleed on Saturday evening. It was a trickle of blood with some small bits of tissue in it. Took about 3 hours to stop. The vet said that's pretty normal but to book him in for a scope to check for mycosis given there was no obvious cause.
On Sunday horse had a couple of very small bleeds that clotted quickly. This morning totally clear, this evening a small amount of slightly snotty blood. He has been behaving completely normally throughout - eating, alert etc.
Given the snotty nature of today's discharge I'm wondering if a sinus infection is the most likely cause? I don't know much about mycosis and can't find much either but I don't think it involves snot? Wondering what experiences others have of these kind of symptoms?

Not a good experience sadly.
Started similarly, scope showed nothing, he was happy in himself. Vet suggested he'd had a bang to his head & should stop happening after a week or so.
Anyway, bleeding got more frequent & then I found a small lump just behind his poll. Vet came back & by this time he was also finding putting his head to the floor slight uncomfortably.
It's a bit hazy what exactly happened from there, but was pts a few days later.

I had a horse with guttural pouch mycosis. We had no warning bleeds at all. In hindsight, that winter he'd been harder to keep weight on than usual, nothing sinister but just slightly ribbier than a usual winter. He'd also had a snotty nose for a few weeks, and was on a course of antibiotics for that. We were just getting to the end of the 2 weeks a/b's with no improvement and I was going to call vet back when his carotid artery ruptured one morning and we had a murder scene in his stable.

Amazingly, we stabilised him and he was operated on the next day and was right as rain afterwards. The fungus had eaten through from one guttural pouch to the other and through the wall of one branch of the carotid artery....

OMG how lucky was he!?

He really, really was! I was late turning out that day, I'd hung around at home to do an early morning conference call with Asia and so turned up around 8.30 instead of the usual 6am. If he'd gone out at normal time, I wouldn't have been back until the evening and he probably would have bled to death in the field.

Wow! I would not have wanted to turn up in the morning to that.

I had a friend whose horse had mycosis and by the sounds of it a clued up vet caught it early. He was backwards and forwards to hospital for weeks though.

Scope showed everything clear and healthy, phew. Vet thinks it must just be a scratch in one of the outer parts of his tract. She looked at sinuses, guttural pouches and larynx.

One of mine had random nosebleeds at the same time of year for several years at our old field. Nothing since we have moved…no idea still what caused it! Never caused a problem though.
