Gosh, I am so sorry u r having to go threw this. I really think maybe trying the warm soaks. Maybe everyday for awhile 15 to 20 minutes. I like 82 degrees. I don't know what other members Temps r That they like to do but Daisy likes it. Relaxes her. Not to deep. Good luck buddy.
I have no experience with Torts. I lean to agree with Tom. Fluids and soaks to flush out system. Maybe ask Tom about Watermelons since that is mostly water. Get Tortellini to pea more. Just a thought. Dont want Tortellini to end up with Diabities on top of everything else
