You go and pay for the service rendered. No different than taking your dog to the vet or replacing a flat tire.
You pay for visits with cash. Most areas have clinics where you register for a means test, and then an appointment costs $10 medication (however much) another $10. That is for the unemployed. If you have a job you can often bargain with many physician's for the visit. Wal-Mart seems to give excellent discounts for prescriptions. You really shouldn't let a bacterial infection continue.
Go to ur local county health department....they'll give u free or discounted services.
