It gets not just better but GONE once you heal completely
I do not want to scare you, but sometimes fissure closes on surface and not completely to the muscle and needs time to do so ! Sometimes fissure is present but not seen during an exam
I healed many times before having a LIS and in my opinion where there is a discomfort- there is a fissure , no matter how small (unless , of course one has hemorrhoid problems or any other condition that can cause pain ).
No pain of any kind = complete healing
Discomfort = something is still going on *sigh
Constant muscle ache = muscle is spasming most probably tiny fissure is still there or it is not healed 100 %
(unless one has pelvic floor muscle problems and has chronic pain in pelvic area but that feels different than sphincter muscle pain )
BUT - please try to concentrate on a fact that your fissure got MUCH smaller, if not almost 100% gone
. In a week or two it should be closed completely and you will be pain free
Just be very careful you do not re-injure the area - keep that poop angel soft and continue with creams and or soaks or whatever helped you heal this far
