Minortities treatments At ER

I was having bad headache. I suffer with Hempiplegic Migraine. I went to the  about 2:00am for help. After about 6 hour of no relief, I ask to be dicharged to go home an contact my Doctor. 3 minitues from drive off the ER parking lot I was arrested.The ER had call the  police on had me arrested , brougth back to the ER for a Drug Test!!! I am a black  woman,it was as if they were saying I was only in the ER  for drug to get high off. We are still in court for the DUI charges against me,but I do plan to seek justice aganist the hospital for a false arrest. Has anyone one else expriecne this?
