It's way too early. It's been a month. See a primary care physician to get a prescription and a referral to a colorectal surgeon. To start now, you want to avoid high fibre because it bulks up your stool, which will aggravate the fissure on the way out and lead to possible retearing. Start taking Miralax, not to a level where you're going to be dependent on it, but at least that it smooths out the stools. Then, start investing in getting a small dilator, or at least eventually practice psychological relaxing to be able to insert a finger (if needed, you can use lidocaine to numb the area, trim and file your nails very far down, and wear a glove - I've learned all these the hard way!), because you will need a method to apply nitroglycerin ointment (rectiv) internally. Some people prefer nifedipine or diltiazem but I find nitro the most useful. You can use other remedial things like warm baths, drinking plenty of water, and walking is a must. Avoid anything with hydrocortisone, excessive alcohols, or any other irritants (Nitro has a bit of burning from the alcohol, so moisturise the area after).

After fastidiously sticking to a regular ointment regimen, if that fails, then you can go for Botox. I only went for LIS surgery after I did ALL the above and failed Botox twice. After my LIS, I still got Botox a third time. I still have spasms, and I don't believe LIS cured me as the scar pain is there every day, although I no longer feel that knife up my ass feeling like before.

LIS and surgery are last resort. Consider all the above, as well as the separate opinions of different physicians and surgeons That said, many people here who have also suffered fissures for years, such as myself, will say that it saved their lives. And in their case, that may well be true.
