I have been having bowel movement problems for about 10 days now. It started out as not really needing to go. Then after about 5 days without a movement I finally had one, but it was difficult. I changed my diet to a high fiber one and much more healthy than it was before. Today I have had the constant feeling of needing to go, but nothing will come out. Knowing better of it, I began to strain some and saw blood in the water after very little happened. Any suggestions?
