I have a question,I am scared! for about 4 days I have been Constipated bad.I was so constipated it took 3 days to really (sorry) get it all out.I was constipated yesterday also,I have changed my Diet BIG TIME!,and I only eat really once a day,and that is the evening.Now a lot lately I have been walking up to 6 miles a day,running the bleachers, This evening I felt constipated again, i went to bathroom only to find that I had stool with a little blood in it. I do not have any External hemorrhoids,as I have checked. I am NOT hurting,I am NOT Cramping,I am NOT bleeding a lot.Only when I had the small bowl movement I had tonight which was only a little.There is NO History of colon Cancer,and NO it is NOT bright red,or Black. This has NEVER Happened before,But then I was NEVER constipated as bad as I was this time. I have in the PAST had external hemorrhoids.But as I said I was VERY Constipated for a few days, trying to have a bowel movement. Now before you suggest, Are you SURE you aren t on your period? Positive. I know the difference. Now like I said I was really constipated, and the stools were large and/or hard.I also must admit I have been Pushing myself Very hard in running,and speed walking,and this diet bit. PLEASE I am having a panic attack here... I have been straining to go to the bathroom as well.I have changed diet HUGLY,I now only eat once a day ,and sometime not even that,Lately I have not been drinking alot of water,My anus does not hurt,no pain at all.Only noticed this little blood this evening
