Phenylbutazone use in facial swelling?

Question

My 10 yr. old Quarter horse had been bitten by tons of bugs while in the pasture. His face was covered in bumps and he just scratched like crazy. I've been applying a mixture of crushed Phenylbutazone (1/2g) to 10 oz. veggie oil. This keeps the flies and bugs away and has reduced the bumps (they are almost gone), and with a light application of Cortaid, the itching has decreased. HOWEVER, I have seen that right under his chin (between his jaw lines) he has a larger than normal swelled soft lump. Almost like a swollen lymphnode (if one is found there). I can tell he has scratched this area profusely. So my Q is this....can I give him Phenylbutazone crushed in his feed to reduce this swelling? If so, should I give the maximum amount of 3g per day or just half that amount. I've given this to him when his ankle showed signs of swelling,as per the vet but not sure about this one. Thanks

Answer 1

the bumps you are treatinf could be small local infections or simply irritated areas from the bug bites and the lymph node like swelling could be a reactive lymph node. I would suggest you to observe it for spontaneous recovery and call the vet if it psersists or worsens good luck
