Would you believe it took me a good year, actually a little over a year to heal completely, My doctor/Gastro, Doc, had title me as acute fissure with mild Diverticulitis and a couple of hemmies..(sounds like and a partridge in a pear tree..lol.)
Please read up on all the posts in this forum on fibre and it's placement to healing, soluble and insoluble.
You can read my post ," The road to healing", as well. Its been over a year and Iam getting stronger every day..no pain, but I still have an occasional IBS bought , some hemmies flare up, over all it's under control, I eat my soluble(acts like a sponge,absorbing toxins) first then follow with insoluble foods (has a brushing motion and sweeps out the waste).
Try cooking with coconut oil, and a good pure unprocessed virgin olive oil, combine the two, too make a healthy stir fry, two natural lubricants for the colon that works over time.
Remember no question is stupid...Oh vay , when I remember the question's at the time I asked when I was in pain and suffering...I do know, although I didn't have any surgery , I didn't think I would ever heal. but I did, and your situation sounds familiar to mine, so I know you will heal..it's just gonna take time and there will be set-back's. be patient,you sound like your healing slowly.
