Has your tortoise had a bowel movement lately? Sometimes when they get the feces really packed up inside it presses on the nerves and causes the swelling like what you see around the cloaca.
It might help if you were to put the tortoise into a large tub, like your bathtub, with warm water. Hopefully he'll scramble around and do a lot of walking/climbing trying to get out, and this helps to move everything along and out.
When I said "large tub" I meant something really big. I mean as big as the bath tub you use to take a bath. You want a lot of room to encourage the tortoise to move around, walk around, try to climb out, do a lot of moving. All this moving in the water helps the poop to come out. It looks like your tortoise is eating the substrate. He needs hydration.
I would not use antibiotics unless I knew for sure the tortoise had something that required the use of antibiotics. And I definitely would not use un-prescribed antibiotics.
(Dorrie: the poop just looked to me as if it contained substrate)
Temperature here is 29-31 degree c, humidity 75-85, I have a water tray 24/7 in the enclosure, soak him every single day, eat mazuri or sudo tortoise pallets daily mixed with chopped dry hay,
Is this pic shows he is getting better or getting worse?
His bowel movement normal for everyday, he even pass urate today. I had been applying thin layer of the antibiotic cream and it shows sign of drying on the previous swollen part.
Dorrie does not look like that. She's a little fat around the hole but that peeling skin... that looks painful.
Did her vet prescribe Fucicort? Isn't that for humans?
"Fucicort is a type of topical cream that is used to treat fungus. It uses fusidic acid and betamethasone in order to reduce inflammation and fight infections. Fucicort can be used for psoriasis, eczema, dermatitis, and lupus. Although it is effective in treating skin conditions, long term usage of the cream should be avoided. This is especially true for children and infants since they are particularly prone to systemic absorption, which can cause adrenal suppression."
"Hypersensitivity has rarely been encountered. As
with other topical corticosteroids, prolonged and
intensive treatment may cause local atrophic changes
of the skin, such as striae, thinning and dilatation
of the superficial blood vessels, particularly when
occlusive dressing is used or when skin folds are
involved. Systemic absorption, sufficient to produce
hypercorticism/adrenal suppression, can occur with
prolonged or extensive use, especially when used
under occlusion/napkin. Infants and children are particularly at risk."
