It's happening again - butt pain

So two years ago I had an abscess. A couple of surgeries, a bunch of antibiotic treatments, months of missed work, 3 setons, and started Remicade, and I got back to normal. Now, I can feel a pain in my other butt cheek. It feels very similar to how my first bout started. Is there anything else it might be? Anyone have any ideas? I'm going to call my doc and I'm sure he's going to send me for an MRI to see what's what, but I don't think I can do this again...
