Carolineandy sorry to hear that you are suffering with fissures, you are not alone. Most of us are here because we have also suffering from either fissures, fistulas or hems.
I know that anxiety and the worry that you feel while wondering why you are in so much pain and suffering from this affliction.
But like I say you are not alone, we all been there, are working on getting better or have been healed.
Sadly pain is part of most chronic fissure suffering.
Irritation after BM, blood in the stools and water and the spams they all go hand in hand.
If you are having problems with the cream tell your doctor to give you an alternative or to refer you to a proper CRS.
Also, if you do not have hems, you do not need to use anusol, any creams that are for hems will hinder the healing of a fissure because you need blood in the anal area to heal and hem creams reduce the swelling suppresing blood flow.
Use vaseline to make the BM easier to pass, lubricate and avoid irritation.
Pain killers helps with the pain when became unbearable.
Is light at the end of the tunnel, either you can find a routine that will help for you along with the proper prescribed cream.
Fissures can be very painful but you can make your life more comfortable.
Is plenty of information here that shows you how many of us has found ways to deal with fissures, it helped me and I still have my fissure but It's not as painful as before even occasional re tear.
Many other people also post about their experiences with surgery, while others post of how they have healed on their own.
When I felt like it was the end of the world for me I used to come to the forums and read about all the wonderful stories about healing, that gave me hope.
I wish you the best and that you find a way to cope with this condition.
