Fly bite or something else

[Tacobell]

Hi all ,
Horse came out in these lumps in one area yesterday . Site is quite hot to touch so I gave it a cool bath with hibi scrub , arnica gel and sudocream . I also gave some antihistamine tablets that I had in the car . Is there anything else I should Be doing to help this ?
He was/is in a fly rug and fly sprayed so I can only assume something crawled underneath unless you thing it’s something else ?

Has he rolled in nettles?

It looks more like he’s came into contact with something and reacted, doesn’t look like a fly bite. As long as it doesn’t spread it should be fine.

Rainscald? Perhaps hot and sweaty under fly rug..it can happen…or some critter got stuck and bite numerous times???

Some fly sprays shouldn't be used in direct sunlight.
Too hot under rug.
Could have rolled or rubbed on something.
Substitute sudocreme for flamazine. It will block up the hair follicle and delay regrowth of coat.

Have you been riding and he's reacted to what you washed your saddle cloth in? Just a thought.

I wouldn't put anything on it, it looks like an allergic reaction and you don't want another reaction to what you put on it.

Hi all , just an update on this . The lumps got smaller and then got little scabby heads on them . Vet put him on course of antibiotics, finished course on Fri and within 24 hours they were back in big lumps like on the first day and had spread . Back on another course of antibiotics and lumps gone down and now just scabby heads . Any ideas?

Possibly folliculitis
