Thank you all so much for your help and advice. It has been brilliant. I think its a good case for showing the difficulty and art of reptile handling!! I hope that this thread can help others by showing problems that can happen etc.

Humidity much better now but its difficult withought overhead light to get the air temp up, the surface temps are controlled at 80 degrees at hottest so that where he contacts the floor/side viv he doesn't burn. the viv is completley wooden with only glass doors at the front so heating primarily with mat under one side tank.

Have a bulb socket/cage in the tank but he climbs on it and so i don't use it as the metal cage over it gets too hot.

currently using digital thermometer and thermostat. I will put up some pics of the tank set-up soon so maybe someone can advise on how to increase the air temp and not the floor temp so he doesn't burn his belly again........

So HEALTH up date : he's been doing really well. the little swelling that was visible went down just after the antibiotics they really seemed to help ( i reckon any later and he may have developed serious infection to boot!!)

He's now eating regularly and very interested in everything, back to his attempts at escape artistry when hes out of the viv and active at night

He drinking (and peeing lots) which is good and enjoying regular baths in his bath bucket and in his bather in the tank and has SHED PERFECTLY. The new scales have shown some miraculous healing of the original wounds- there's a visible scar but i am so happy its improving as quick as it has (vet advised they can take a long while to heal)

Will take and post some pics soon so u can see the amazing recovery so far....

thanks you all again for you help
