Is there another, more effective product that I could use to remove the intense pain? When will the pain go away?

Hello! I am 30 days pregnant and I am taking syntroide. For the last 6 days, I have had external hemorrhoids. I even think that they are thrombosis hemorrhoids because it is very painful and the lump is big. The pain prevents me from functioning normally and does not really go away. I use Anusol, I take baths, I sit and lie down, I don't force myself, I'm not constipated anymore, I'm at rest, but I have the impression that it's not getting better and it's already been almost a week.
