Oh what a day you had! Piles, understand that one sometimes to often. Always of course check with your nurse or doctor, but it sure sounds like you were / are constipated. I am just another COPDER but have been in your shoes more times then I would care to talk about LOL. The little bit of blood that you saw was more then likely caused by the straining and coughing while your body tried hard to get rid of all excess you had saved up. Our skin inside our body can only take so much pressure to before it gives out a little. What I have been told over and over again, a little bit of fresh blood ( red of pinkish) is normal from all that action going on. Usually am told to hydrate more, eat more fiber, get more exercise and if all else fails take an over the counter stool softener one that either your pharmacy can recommend of your medical team. IF there is a lot of blood or it continues, dark black looking stool, now would be the time to get medical help ASAP of course. Be aware of the constipation, this could also bring on hemorrhoids and they are no fun to have to deal with either, many people suffer from them and they can be brought on by straining to much, even pregnancy can cause them..
Now a little fun fact for you. There is 3 board games you play in the bathroom / loo, their names are Concentration, Aggravation and Kerplunk. Yes they are all true board game but fitting for this situation LOL Hope you are feeling better, no be surprised if there is a little stinging in the poop shoot for a couple days. My your day be better tomarrow.
