For those without Health insurance everything is a lot more difficult. Fortunately some Central Illinois communities are providing help for those in need.
In Bloomington, BroMenn Family Health Clinic and the Community Health Clinic help those who are uninsured or underinsured.
In Peoria, Heartland Community Health Clinic is available.
In Champaign, a recent News Gazette article highlights the Champaign County Christian Health Center. A group of local churches with help from businesses provides health care for those who have no insurance.
If any one else knows of other resources in Central Illinois please let me know.
