Anal fistula

Alrighty so I think I just need to express my worry with this.

3 weeks ago I noticed something that I thought was a cut in my actual Anus but when it didn’t heal I looked and saw a hole, like a actual hole, on my anus.

After I took to google I read up about anal fistulas and it’s just what I think I have because most things line up with it.

So I booked in to see a doctor that wasn’t my usual GP because I was embarrassed, she looked and told me it was a hemmeroid and said she can’t see a hole.

I used a cream she prescribed me but it didn’t so anything and now I’ve booked in to see my actual GP tomorrow because the hole isn’t going away, it’s bleeding and hurting so much.

At this point I’m honestly really worried.

Has anybody been through this? Does anybody have any advise?

I’m just so stressed

TIA xx
