could an allergy only cause itching at night? This is driving me insane!

[Ang93]

For almost 1&1/2 years My butt has been itching right on the anus almost every night. At first when it started it would itch a little an I wouldn’t think anything of it till about 4 months in it started getting worse even to the point it would itch in the middle of the night while I’m sleeping causing me to wake up. Now the itching has gotten better but it hasn’t completely gone away it still itches almost every night just not as severe. I tried every over the counter item you could think of to try for my butt and none stopped the itching. I even tried pinworm medication twice. The only thing that helped somewhat was taking AZO the kind for yeast infection but if I would stop taking for a day or two it the itching would come back. I also tried sensitive detergent Incase I was maybe allergic to my bedding and that didn’t stop the itching either.

About 6 months or so ago I went and seen a hemorrhoid specialist thinking that was what I could have since at first when I started having this problem it was like I my poop would be super big like too big to come out and I would have to sit on the toilet sometimes for an hour or more and it would hurt very bad and I’d have to just pain through and force it out to stop the pain and sometimes because of that I would even bleed (until now about 3-4 months ago all of that just randomly cleared up and I don’t have that problem anymore just the itching). The dr didn’t notice any redness or hemorrhoids. The only thing she could tell me was maybe my butt hair was too coarse and that could be causing the itching to try laser hair removal (didn’t try cause 1 I thought she was crazy and how could that be it if it hasn’t itched years before from my butt hair(never shaved before so I can’t be itching from razor shaving) And 2 you have to pay out of pocket for laser and it costs too much) so I went back asked for a prescription for a cream to try and she gave me proctzone (spelling?) that didn’t do anything either to help. I still had the problem so I found a new primary doctorthan my regular one and went to her for a second opinion and she looked at my problem and said she didn’t see any redness or irritation and that it could be anxiety. (But thinking I’m never anxious in my own home and how could anxiety cause my butt to itch and every single night and only at night and not just occasionally?) I went back for a follow up appointment and she had me swab the area to send it to get tested For any infections. And results came back that I didn’t have any infections or diseases.

This is really annoying because I’d really like to find out what could be causing this problem and I feel like I never will solve this. It’s weird that it only happens at night time but it’s not pinworms. Can anyone give me advice on what could be causing this or what I could try that I haven’t yet. I’m desperate to try anything at this point!
