One thing that puzzles me, is that you write that you had your fissure for two months, it healed, and thats 4 months ago.
Usually a fissure takes at least a few months to heal but you make it sounds like it happened overnight? Can you maybe tell us a bit more about this?
Anyway, if you really have been healed for 4 months, I would say, any pain beyond 1-2 on a scale to 10 sounds wrong, and should be looked at.
