Can CL bumps go away on their own...?

I have a buck that seemingly overnight developed an abcess on his cheek early this year. I was worried it was CL at first but then it started to get smaller and slowly disappeared and was completely gone. I did check often to make sure it hadn't burst and it never did, It just got smaller until it was completely gone. So I thought maybe just a tooth abcess or that he got poked with hay or something minor.

Now a few days ago, We were letting the goats outside and I noticed a pretty big abcess in another CL spot, In front of his back leg. I freaked out and immediately separated him. I've been keeping an eye on it to see what happens and was planning to lance it as soon as I can get help to do so. But tonight when I checked, It's noticeably smaller. Like MUCH smaller. In fact I didn't even see it first, Checked his other side and it wasn't until I double checked the first side that I found it again. Again, It hasn't burst, There's no openings, no pus or anything. It's a soft and squishy abcess and has been since I noticed it a few days ago.

Is it possible for CL bumps to dissappear without bursting or being lanced?
If not, Any ideas what would cause an abcess like that near his leg?

What should I do??
