If you haven't already gone to the doctor (you certainly should over the sinus problem--you could say saw dust irritated it days ago and it's gotten worse), I just wanted to provide a different perspective on the bloody stools--if it was fresh blood in your stool, it's not necessarily serious, particularly if it happened when your bowels were stimulated. I have what could probably be considered irritable bowels and they are very sensitive to caffeine and, to a lesser degree, most other stimulants with coke being a close number 2 (I'm so sorry for this pun). Put simply, stimulated bowels can push not-yet-ready logs downstream prematurely with violent, explosive results. Bleeding often occurs in my case (I'd say 1 in 3 times following a cup of coffee) if these premature, soft, sometimes formless stools propelled by excess gas and increased involuntary movement push less hydrated (the colon sucks up excess water), ready-to-evacuate stools out in a manner that can cause superficial tears--NOT the kind that leaks waste into the rest of your body resulting in septecimea. While stimulant-related bleeding is most common for me to experience while under the effects, as described above, I also pass the same fresh, bright-red blood after "holding it in" despite the pressure and going after the stimulation has subsided. I haven't reasoned out exactly why the delayed bleeding in that scenario occurs, and I can only say the outcome is the same: a premature, explosive evacuation that still manages to tear the lining.
By all means, mention that part to the doc as well, but if he doesn't realize you're a recreational stimulant user (or isn't familiar with explosive diarrhea resulting from drug-induced bowel stimulation), he could overreact and send you to a costly specialist, which tend to carry a very pricey co-pay for visits these day, if you're insured. If you bleed again and during a normal, peaceful bowel movement, you will definitely need to follow up on it with your doctor. Black stools, on the other hand, often contain older blood, with generally more serious implications pointing upstream. This is simply my experience. I would wait for further indications of a bowel problem for now and just let him know about the sinuses. Two cases of internal bleeding with a doctor unaware of the likely drug-related, fairly common cause of both is asking for an overreaction. Your sinus problem, however common among frequent intranasal users, does sound much worse than a typical cocaine nosebleed or DMT-irritated throat.
