“Why do I have pain every time before passing my bowels?”

Abdominal pain is one of those issues that has so many possibilities as to why it's happening that it is very difficult to answer that question over this medium. My advice is to see your doctor or GI specialist. A colonoscopy may be in order.

You may be experiencing IBS (irritable bowel syndrome) or IBD (inflammatory bowel disease). To determine what issue exactly you're currently experiencing, we recommend seeing a primary care or a pain management physician. A doctor will ask for your medical history, travel history, sex, drugs, and smoking. A further exam can confirm or give background for further knowledge about the disease. If there are concerns of potential inflammation in the bowel, you may be ordered some lab tests.
The most important thing to remember is not to live with pain, but rather seek help immediately.

Need to see a GI physician for that.
