Pain relief?

This is my first post here and I could really use some help with pain management. I have struggled with fissures for as long as I can remember, but they have recently become so debilitating that I am unable to work or even parent my little boy.

Since November I have had 2 severe fissures. My first fissure led to an abscess that then developed a fistula which requires surgery. The second fissure is so deep that the colorectal surgeon stated she could see the muscle. She said that I will need surgery for it as well and after a colonoscopy and MRI it was determined that I have anorectal Crohn’s disease. My biggest problem with all of this is no one has been able to do anything to help me with the pain.

My surgery isn’t for another few weeks and I just don’t know how to deal with. I can barely walk or even get out of bed some days. I do sitz baths twice a day, use Nifedipine 4 times a day, lidocaine, Tylenol, muscle relaxants and even tried Tramadol, but they do nothing. Is there something I’m missing?
