I am suffering from piles and irregular bowel movements only during and after my periods since last month. Had first observed external piles two years back, but didn't cause any pain or discomfort after that one times. I live in hostel and my eating habits are a bit untimely and irregular. Currently using Pilex ointment, which soothes the pain to some extent. Is there a link between periods and constipation? Can piles be cured just with medication and without surgery? What medication can I take up to reduce this situation?
