Mocha's Anal Sac At-Home Treatment

It's been a few days since my initial post about Mocha's anal sac that ruptured.  Every morning I clean her bottom, wipe away the part that crusted over the hole, and clean the area as much as possible. In the morning, I am the only one who can handle Mocha and treat her behind so it's nearly impossible for me to hold her in place, stop her from squirming, lift up her tail, and flush the hole all with one hand. I've tried it and it's not working.  So instead, after I clean the hole, I put warm compresses on the area that is treated with the flushing liquid.  After the warm compresses I fill the hole with the medicated cream.  This routine in the morning is working out well and she's not as upset with me.  Our two other treatments involve flushing and all the treats in the world do not calm her down. However! Tonight after a bit of squirming and warm compresses (I get her used to me being back there with the warm compresses and she seems to like it), Mocha let me get the entire syringe of fluid in the hole without freaking out.  Progress!
