Update! Took Rodney to Tilehurst Vets to see Jenny Towers - Jenny was caught behind in surgery so he was seen by a lovely vet called Amber who was amazing, and checked with Jenny throughout.
He has an abscess, which was drained on site. The goo is being sent off for live culture tests to make sure he gets the right anti biotic.
I'm taking him back next week, he may need a tooth out if its been caused by a tooth root abscess, but we are giving him a few days of new anti biotics & anti inflammatory.
He is back home & has eaten dinner. He was good as gold & everyone fell in love with him.
So getting there, altho he may end up having a tooth out next week. I'm going to read up on this...
Had I continued with my local vet he'd have half a face by now, they were planning on butchering him this morning & had they found a tumour wouldn't have woken him. Tilehurst remove tumours all the time.
Word of advice if you are ever in this situation, go the extra mile to a decent guinea friendly vet. He's got a way to go, but they were very positive & I feel will be well looked after. I am VERY relieved I made that trip!
Here he is after his busy afternoon!
