african grey not using leg

by Duncan
(Stafford,UK)

on nov 8th my african grey got spooked & flapped around in his cage, the metal ring dug into his leg & made it bleed.
i took him to our local vet, as the avian vet wasn't available until the next day. they removed the ring, & they prescribed baytrill.

The following week 14th nov i took him to the avian vet, who said that he needed stronger antibiotics, he also had antibiotic injection, & painkiller injection. However he seemed worse since then, & now can't stand on the foot, or grip his food. The leg has a lump on it. He seems happy enough in himself, but we are having to feed him, as he can't get around. What shall i do next?

His current medication is marbocyl 1% sa inj 20ml, 1ml in 100ml water daily, loxicom 0.06ml by mouth, & noroclav 50mg, which contains 40mg Amoxicillin, & 10mg clavulanic acid , 1 tablet daily. Do i need to take him back.
Thanks
