I was having chest pains so I called to see if I could get and EKG and made an appointment at the clinic, even though the receptionist thought I should take an ambulance to the ER. I didn't think my chest pain symptoms warranted a trip to the ER, but in the end, I ended up going from the clinic to the ER because as the doctor put it, "they weren't equipped to do what it takes to check everything for chest pain."  I have had other friends who had chest pain, and ended up getting stints put in, & 2 of them ended up dieing, so I just was being cautious.  All of the doctors and nurses that took care of me were absolutely amazing, professional, and made me feel comfortable all of the while I was there.   When at the ER, they took care of all of the tests so fast that I was in and out within a short period of time. The tests proved that I wasn't having a heart attack or a stroke, so that put my mind at ease.  The only drawback/concern was that the doctor recommended that I take an ambulance from the clinic to the ER and I just didn't feel that that was necessary, but he was just being cautious. (I signed a form saying I was declining the ambulance ride, even though the doctor recommended it.)   I called my husband and he took me from the clinic to the ER, so all worked out well.
