I've been lurking on here for a few months but thought I would join and share my anal fissure healing journey in the hopes that it will help someone.
Background
I experienced some bleeding during bowel movements in March 2020, these were 'minor' compared to the one I have now and within a few weeks would heal. However, a new fissure opened in March 2022 after I had 2 really large portions of cognac noodles (as someone who was going for a gluten-free diet, I wanted to try something new but oh what a mistake that was). The next day after eating the cognac noodles, I had the worst constipation ever and really strained to get the undigested noodles out into the toilet bowl. That was when I noticed a whole bowl of blood and lots more upon wiping.
What I did
With my previous experience of anal fissures, I thought this one would heal quickly too. But after a week, I decided to see the GP who examined my anus and confirmed there was an anal fissure. I was prescribed Rectogesic ointment and was also asked to increase my fiber. I was already taking psyllium husk capsules (6 per day) before I knew of anal fissures so continued to do so.
1 month after
The Rectogesic ointment would give me headaches as I applied it within the anal canal with a q tip but I persevered and did it twice daily. However, I was still constipated and bleeding. Was it because I had decided to go vegetarian this year? Was it because I had cut out all meat aside from the odd seafood? My stools were bulky and hard to pass. As a person who only ever drunk water and no coffee or tea, I was stupefied by why I wasn't healing.
Mini week of no pain?
After a month, I reluctantly went on a one-week trip to Mexico. I was scared that going off my routine would make the anal fissure worse but surprisingly my stools came out like toothpaste while I was there. What was I doing differently?
1. As I stayed at a hotel, I had the same breakfast of omelet, some refried beans, and some fruits and vegetables in the omelet such as tomato and onion. I would also take a glass of orange juice followed by taking 2 capsules of psyllium husks.
2. I also walked for most of the day as I was traveling and lunch would be Mexican food such as tacos, enchiladas, 'sopes', (corn based flour, meat, cheese, and some vegetable garnishings) as well as the occasional seafood. I rarely had any grains such as the usual white rice I would eat or oats for breakfast.
3. During the night, I would eat very little but it was always very alcohol filled. More cocktails and hard spirits.
I noticed that I didn't take the psyllium husk tablets after I had left the hotel for the day and didn't apply Rectogesic at night as I thought it would interfere with the alcohol.
Back to blood
I then came back home and resumed my diet and noticed that I would have constipation again and even more pain and bleeding (which led to me howling in the toilet for most days

What I am doing now - June 7th 2022
Thinking back, I realised that maybe I should revert to the diet I had in Mexico with eggs, seafood, meat and some vegetables. I saw a video on how psyllium husks would bulk up the stool if not taking with enough water so I have stopped taking these completely.
1. I normally have a bowel movement in the morning or I induce it now with prune juice and magnesium citrate tablet the night before. I have a warm shower and apply coconut oil with a finger cot before the bowel movement and while doing so I can sometimes feel the tip of the stool which I try to mush but it doesn't always work. The blood and pain is still there so I am not sure whether I should use vaseline which worked in Mexico but is it good for the anal canal? I take a sitz bath afterwards but it stings rather than relaxes my anus

2. For breakfast I am trying eggs and a fruit. For lunch, I try to go with a meat or fish with some vegetables and prunes I take my magenisum citrate tablet here. For dinner, again I go for a meat or fish and some vegetables. I heard that meat or fish will give smaller stools than if I had too much fibre which would give a bigger stool.
3. I do a daily walk.
I feel so alone and drained but it is nice to see a community here! If you have tips please do share and I know we can heal together :)
Will try and update again tomorrow.
