I'd be trying another vet. This dog sounds miserable. Could have something else going on in her pelvis, bladder, have worms or has a tumor, etc., besides the anal sacs. I'd be getting a full work-up and even x-rays. This could be bad pain or a bad itching. A vet needs to get her relief with pain medication or steroids or something. You sound miserable. Get her a second opinion with a respected vet and let them get a diagnosis, then treat.
