I have large intestine obstruction with constipation and piles. Please suggest medication.

Hello doctor,

I am 36 years old. I have a problem on the right side of the large intestine. I have four babies with cesarean surgeries. My youngest baby is 13 years old. My uterus was removed five years ago due to rasoli. After this operation, I felt pain in my anus and a year later I was alright but later on my mother suddenly passed away. Due to sorrowness, I felt pain in my stomach and a pull in my belly. Followed by I had constipation and piles (no bleeding). Now whatever I eat or with empty belly I feel heavier on the right side of the large intestine. After eating something I feel that it has blocked due to any hindrance. I thought it may due to eating beef or meat but now doctors say that my large intestine is infected and even using medicines show no improvement. My hunger is normal but I have constipation and little pain in the right intestine with a large amount of urine with crystals in it. Please suggest medication.
