From your description,I feel basically ur prob is connected with mainly constipation.
Avoiding going to toilet when you feel like going,for some reason,makes the stool get dried up and getting hard because of acids in body.Which causes pain in stomach and anus.
These small little things/habits and constipation are also connected with the fat deposits in the arteries,resulting in high B.P.
Drink a plenty of water and go to clear your bowels whenever the body demands it.
Take care!
