Mother 70 yro disabled woman has to have pain injections and will not be able to drive herself home. Is there a transportation service that can assist?
Contact your local Area Agency on Aging. They generally have information on transportation. If you are having problems in other areas they can do a needs assessment to determine services needed and help direct you to the appropriate services.
