I am a 70 year old female, who was having sharp pains in my right side near my naval. Went to ER and had it checked out, had a |E|KG. blood work urine sample, cat scan, we are thinking it could be appendicitis. But tests ruled that out, they did find a slight infection in my bladder. Came home with no positive answer to what it was. But I do suffer from constipation, so I took a laxative last night, did have moments throughout the day. Then I started having explosive burst of diariah which the last 5 times has been nothing from blood in the toilet bowl. Shat should I do now?
