At the beginning of November 2014, I began to have an itchy anus. It started unbearable, and continued to be more and more unbearable as time went on. Convinced it was hemmorhoids, I tried every home remedy I could without alerting my parents ( I was 17 then, now 18, still living at home). I tried Vitamin E, Vaseline, Ice packs, and Tucks pads, none of which really provided any lasting relief. Yesterday, as I sat in my room in pain, unable to even leave the house due to my ferociously pulsing anus, I had a revelation. I suffer from mild seasonal allergies, and took Allegra, Benedryl and Claritin regularly from September to the beginning of November (I'm American, and for clarification, these are OTC allergy medications).
Anyway, right around when I started to take these things, I ordered Kirkland Brand Fish Oil, a very low quality brand, as it was also the cheapest by far. I have been taking it since mid-September. I also have a shellfish allergy, but I assumed the fish oil wouldn't kill me, so I continued to take it. After I stopped my regimen of Allergy pills is when my Pruritus Ani began. I did not make this connection until last night. I then took 3 Benedryl, providing me with almost instant relief. Now I woke up this morning on the longest streak of anal comfort since November.
My point is, my pruritus ani was caused by the Fish Oil, and I am now stopping my regimen and praising the Lord for having provided the mental clarity that allowed me what will perhaps be long-lasting relief. I encourage anyone with problems similar to mine to eliminate any supplements that coincide with the beginning of your symptoms.
Also, let it be known that the information available on the internet may distract you from realizing the true origin of your affliction. I missed the forest for the trees, so to speak, because I assumed my problem was Hemmorhoids, not my diet or supplement intake.
