OH that sounds awful, I dont know what you can do for immediate relief bu tbe careful with all the pushing as you dont want to get haemerroids!! I have IBS and so I have been increasing fibre intake and drinking loads of water and that helps a lot, also i have flax/linseed seeds on my cereal every day which helps (make sure you drink a lot when you have these).... sorry not much immediate help but maybe try this and see if it helps in the future.
