An unexpected trip to the ER from the mountain on Sunday morning

It was a fun packed weekend with Bonnie & Helena's family at our cabin over the weekend. Shortly after Erica woke up at 4am Sunday morning to go to bathroom, she came to our bed and complaint about cramping feeling inside her chest, the pain didn't go away and I found her heart rate was high... We took her to the fire station near our cabin and 3 firefighters checked on her, as precautionary measure, the firefighter call for ambulance from Frazier Park. The ambulance arrived in 1/2 hour, the paramedic checked Erica out and her condition has improved. Just to have a peace of mind, we decided to send her to the hospital to have a more complete check up. It was 1 hour 15 minute ride to go to the Henry Mayo Hospital in Santa Clarita, since it's early Sunday morning, there were only few patients in the ER so Erica got some attention very quickly. They have performed EKG and took an X-ray picture for her, result came back in 1/2 hour and everything was normal. The doctor told us that it maybe due to acid reflux... The ordeal was over in the early Sunday morning and the doctor discharged Erica at around 9am.
