I was playing around with about 7-8 inch dildo, and in some point my anus harshly sucked it all the way in. Didn't feel any pain and I pulled it out, but after few days I had some weird looking stools, first was some sort skin like cubes, and after that over my stool there was tar-like dark stool. Bowels are painless, tho I occasionally feel some discomforting pain, which is pretty small...
I think that black stools are consistent with there being blood in the stool. You could try looking up black stool online, but in any case, you should probably go see a doctor, particularly if you have continued symptoms.
Yes, I now it's probably a blood from possible tearing and I read some about it. It also says darker blood can be serious, But given the fact that it has been few days since I noticed it after the accident, I think blood may have been there around the rectum for some time, and doesn't necessarily comes from deeper colon or stomach... I had enema before the masturbation, and after that I don't usually have to go for bowel for days...
I was under the impression that black stool was caused by blood further up in the digestive tract. Actual red blood being from further down. I'm not a doctor obviously. I'd probably watch it for a couple of days if it were me. If it continues or you feel sick you need to get checked out. Could be a bleeding ulcer or something. Good luck.
Go see a doctor immediately. Black stools are indicative of bleeding up where it shouldn't be bleeding. Do not ignore your body's messages.
And the TMI thread of the year award goes to..... This is seriously your first port of call, asking here rather than seeing a doctor, or posting here before even googling 'black stool'?
I don't want to be a source of scaremongering, but this is definitely a case for professional advice - not a forum of amateurs, such as us. http://www.patient.co.uk/health/rectal-bleeding-blood-in-faeces Note the very first paragraph in the above link:
Thanks, feeling pretty fine, and no signs of weird stuff after that one time. I know is always best thing to visit doctor, but colonoscopy is crazy expensive and no way I could afford it.
Glad you are doing better. Also glad that you updated. The net if full of people with medical problems that never follow when they see the doc or things resolve. My advice would be that if it happens again, you definitely need to get it checked out. Hopefully it never happens again!
