The CVS in Keller on Rufe Snow and North Tarrant Parkway has a Minute Clinic, where you can go to get treated and a prescription for an antibiotic. It would probably cost around $70--cheaper than CareNow. You do need to get treated. If it is strep (which I was just diagnosed with today), left untreated, can cause MUCH bigger problems. You have to take care of you--whatever the cost.
