Glad you are feeling better, and home at least.
Terrible what they did to you. I had a similar situation with my mother a few weeks ago. She is 94 and the medics thought she had the flu and downplayed her weakness and vomiting and told her caregiver to call a family member next time. They wouldn't take her to the hospital. She is 94!!!! What were they thinking? The next morning they called 911 again, and they told her to call an ambulance and left (same medics) she had to go to the hospital, and had a bowel obstruction, needed surgery and is fine now.
I called 911 myself and complained. The fire marshall himself called me several times, and did a thorough investigation. He visited Mom and brought her a huge basket of flowers and did a ton of damage control. He told us to send the ambulance bill to them. He said there would be severe disciplinary measures taken against the chief medic, who was the difficult one. Sure would like to know what he did. They were terrified we would go to the news media and/sue them.
Be sure you report how they treated you. Inexcusable!!
