can an abscess heal without surgery?

Sorry for posting a million questions recently. I am so confused on what to do! So I believe I have an abscess caused by large, impacted stools. I was able to remove enough of the stool manually (not really so much fun) that I don't seem to be feeling discomfort from the stool anymore, but I know I did not get it all. I already have an abscess that currently has a tube hanging out of it for drainage purposes. This new abscess is on the other side. I'm about 97% sure it's an abscess, but there's some hopeful part of me hoping that my tush is hurting from the stool still in there. My options seem to be, continue sitz baths and my antibiotics and hope the abscess goes away. But I can't afford to miss more work, so I need to be fairly sure that sitz baths and antibiotics will make it go away. And I need it to be most of the way gone before Monday afternoon when I see my manhandling colorectal surgeon. The second option is to continue with sitz baths and antibiotics and also try a laxative to clear out the rest of the stool. I have only taken a laxative when getting a colonoscopy along with drinking stuff, so I don't really know how long it would take to work and if it would clean out stuck stool or just force it out and cause more damage. The laxative was suggested by my colorectal surgeons office, along with the last option of going to the ER. That's my least favorite option. Has anyone ever had two abscesses at the same time? I appreciate ANY advice!! Thanks in advance :)

I have had several heal with just antibiotics and sitz baths. Unfortunately, they do tend to come back in the same spot but to get you through for now, those should work. I've never had surgery for them, only had them lanced, but that seemed to solve my issues of them coming back.
