Hi, I have had a few fissures and found that a bidet coupled along with calmoseptine or triple paste works wonders. Initially I purchased a handheld bidet which is essentially a squeeze bottle with a long spout. This helped my skin heal greatly and the warm water is very soothing. https://www.amazon.com/2PCS-Pa...ps%2C334&sr=8-14
Eventually I bit the bullet and purchased a bidet from Tushy and installed it myself, which was very easy. It was fairly inexpensive and over the past month of having it, I've definitely gotten my money's worth. https://hellotushy.com/product...ater-bidet-tushy-spa. Now whenever I have to use the restroom while I'm out, I miss the bidet so much! Wet wipes work well, just make sure you pat rather than wipe and also make sure you pat yourself dry after.
Sitz baths are also great. If you don't have a bathtub you can purchase a small basin that sits on your toilet seat. Just fill it with warm water (as hot as you can tolerate!) and mineral salt if you like. https://www.amazon.com/Foldabl...TG9nQ2xpY2s9dHJ1ZQ==
Another idea is installing a shower head with a removable wand, it makes showering hard to reach/sensitive areas much easier.
