Yes, it's recovered (the tract is closed up but once it's there it's forever and can re
open again or new ones can occur) my GI put me on Humira for it, that's what healed mine....it's not linked to IBS, it's either IBD that can cause them or as you mentioned child birth, but the child birth ones are a bit different from the IBD ones and can usually be repaired depending on the extent, by surgery.
You really need to get it looked after, and be prepared that your IBS may in fact be IBD instead, sadly the two conditions are often misdiagnosed because they are often very similar.
