Seeking Medical Advice in the Metairie/New Orleans Area

I’m new to this App and to the Metairie/New Orleans Area. I’m a teacher and they say I make to much to afford Medicaid but all my doctors bills are adding up and eating me alive. I’ve had this awful pain in my back and have been constipated for the past week. I’ve been taking everything from laxative and stool softeners and I still can’t get out a full ‘passing’.

I currently don’t have a regular pcp
