Worse ER experiences! First time visit 5 hours wait just for a needle shot. They told me they will contact the my doctor to confirm dosage and after 1 hour wait they said they will contact now; another 2 hr 30mins wait for shot.
9/24 doctor told me to go to hospital for another dosage of medication check in at 12:03pm, draw blood at 12:25pm. Since then they left me in lobby for 2 hrs and half then call me to patient lounge and left me for another 2 hours unattended. Finally got Ultrasound done at 5pm, at 5:20pm doctor talk to me about the report and letting me know I ll be getting a shot shortly ever since I been left unattended in the lounge no nurse answer my questions and it s 8:08pm. Unless u r dying or on ur last breath, don t come to this hospital they will leave u unattended till further notice... lol
