What could cause intermittent, excruciating anal pain prior to and
Probably hemorrhoids triggered by menstrual hormone.
Hello dear and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Your symptoms seem to be related to hemorrhoids.
The hormones during your period can cause relative constipation.
This is because the muscles are relaxed in the colon by the hormones.
The harder stool can trigger the hemorrhoids.
I suggest to use a stool softener such as Colace.
I also recommend using an anti hemorrhoids cream such as Preparation H.
For the pain you can use Buscopan 10 mg three tablets a day.
Hope I have answered your query.
Let me know if I can assist you further.
