well I took him to the vet straight after I put the post up:

WIth some light massaging and a liquid expplosion from the rear end of a BP, the swelling has subsided.

A fecal sample an dsaliva sample were done, and the result is uncertain.

Luckily for me I live in Liverpool, and there is a world renowned reptile pathologist at the university Udo Hetzel. With a quick phonecall from the vet Udo very kindly said he would look at the samples. And is doing so as we speak.

The vet think it may be a parasite cryptostomisis?(i think thats what its called) Which doesnt fair well with the BP as there is no current cure for this parasite. Although the vet does have 2 very healthy tortoises with the same condition, that have had it for many years.

Just a waiting game now. Hopefully the worst (listed) above, does not come back in the results from the tests!!!
