5 days ago I ingested ph down(general hydoponics brand), phosphoric acid, citric acid, and mono ammonium phosphate. Company wont give exact recipe. I did not realize I had ingested it until yesterday after determining that my sore throat was far worse than any case of Stept i've ever had, and a friend questioned me about a soda bottle that contained it. I drank aproximately 2-3 oz.'s. My symptoms are excruciating lower throat, and for last 24 hrs-high fever/headache.

I have had only 1 bowel movement since monday(day of ingestion) and that was on tuesday. It was hard and striped w/bright red blood..which I attributed at the time with constipation. My question is: it is now 5 days after ingestion, so is it still an emergency to be seen or am I probably OK and through the worst of it?
