How on earth am I creating antibiotic resistant strep in my own body? I do take the full proscribed course of antibiotics. I don't see what that has to do with having to spend at least $150 (consultation + lab test) just to get permission to get the antibiotics I need, which then cost additional money. While big ag gets whatever antibiotics they want. Thank heavens I work in tech and $150 isn't like a whole month's worth of groceries to me. But there's no way to look at this and think "Yup, that's the system working as intended."
