When i first bought my horsfield i had exactly the same problem. I rushed her the vets thinking RNS and the vet said she was fine. Next morning her nose started to run again (and eyes irritated) so i joined a forum and got the answers. I took out the sand and soil and put in bark (which i washed first to stop dust) then covered my tortoise table with blankets to retain some heat (background central heating not enough).
The difference was absoloutely astounding, the runny nose immediately stopped.
Once tefa was better i experimented to find out the best for her. I`ve found out that even though sand/soil is the best for most tortoise`s it irratates my torts eyes, so mine are now on paving flags (for nails), soil, pebbles and bark chippings for digging.
As they love climbing i`ve made a ladder up to a second floor area in one corner with a big box full of chippings which they bury in of a night and i don`t worry about the heat. I lowered my uvb light to 6 inches and they`re much more active.
Also feed lots and lots of weeds (browse websites theres loads of information) i try not to feed veg and lettuce, (only as a supplement).
I`ve learnt a valuble thing that each tortoise is individual (mine is anyway, lol). What is right for one maybe not right for another, i experimented and your tortoise will soon let you know if it`s not happy.
Hope i`ve helped you somewhat which my experience of this. (I would try this for a day or two before going the vets as i wish i`d done it first as tefa got vey upset at the vets)

P.S: I would let her get used to her new environment and you first before letting her roam on the floor it might be to stressful. And mine seem to be most comfortable at 80-85 at the cool end, anything under they just sit under the light and go to bed early with no other movements. (you can tell i`m in the house all day can`t you, sad, lol.)
