It sounds like you have severe constipation. There are many safe products to try. I would suggest Metamucil (this comes in capsule form as well as a powder) and lots of water. You can get magnesium citrate tablets to get things moving. Most people are deficient in this mineral anyway. You can also use glycerin suppositories for quick relief. Also you probably need to add a probiotic into your daily routine.
The probiotic and Metamucil are healthy habits you can continue, and the mag citrate won't hurt either if you need it in the long term.
