Thanks for the advice. I never thought to compare my stool to others here. I'll definitely do that next time. Hopefully there'll be a match to something.
Your're right btw, my pcp really does care. He offered to give me something for pinworms since I saw little white strings in my stool. He said they don't bother with a confirmation for pinworms and just go ahead and prescribe the medication. You think I should take it?
