In addition to caring for you when you're sick, a health clinic is a good way to learn information you may need to know about immunizations, reproductive and neonatal health, and other health topics that aren't often spoken about, such as HIV screening. Often, you can get brochures on everything you're interested in.
If you live in a rural area, you may be in luck. Some states and rural counties maintain health clinic programs that provide for low-cost health care, especially for the indigent. You can find out if your area does by checking the Internet or by contacting your local and county government.
