PCP: You need a PCP for yearly physicals and you can also go here or to a store like Walgreens for things such as flu shots.
Obgyn: Women need these doctors who specialize in the female reproductive system. They will check for cervical cancer and make sure things are normal with your reproductive system.
Any specialist you may need such as psychiatrist, dermatologist etc.
The majority of these professionals you need to see once a year, you should get a cleaning from the dentist twice a year and go to specialists as much as needed.
For my frequent readers I will be taking a break for blogging for a few months to focus on some other projects. You can keep in contact with me here or through my social media accounts.
