I'm so sorry... How awful you have to go through this after having your baby!! I agree that you need to get better before having another. I have had my fissure for 7 months now and I've been using the ointment for about 8 weeks. I know the longer you have the fissure, the less likely you are to heal without surgery. I didn't start using the diltiazem until my fissure was chronic either. It has helped with the pain and spasms, but I keep seeing blood so I will be having surgery in a couple of weeks. There is another member on this board, Cherylk who has healed with the ointment . She comes on often.
I'm not looking forward to the surgery but I feel like it's the best chance I have to get this over with and I can relate to feeling like you will never get better. I wish now that I would have just had the surgery when I had my fissure a couple of months and I would be healed by now... I feel like I've been drug down mentally and physically for way too long and now I have to go through with the surgery anyway. I guess the bright side of this is I have learned how to eat and what stool softeners will work for me while I'm recovering witht the surgery
Good Luck

I hope you get better soon. I know how hard this is!
