Time it takes: 15 minutesCan't get in and out of the doctor's office in 35 minutes? You can see a physician's assistant or a nurse practitioner in about 15 minutes, or so, says MinuteClinic, one of the largest of the chains of walk-in medical centers cropping up in pharmacies or stores such as Target or Wal-Mart. That's fine for basic ailments like earaches, strep throat and pinkeye. Your insurance may not be accepted, which could leave you footing the entire $59 ear-infection fee. But you can stop by at lunch and not miss hours, or even a day, of work.
