Patient First review: Stay away from this business!

I recently visited the Patient First Abington PA location with a bad lower back pain. I was examined by Dr. Andrea Tse. Please stay away from this "doctor". She wrongly diagnosed me with a pulled muscle, based on her guess after looking at my Xray. She could not answer any of my questions. For every question I asked she gave me the same answer- "I don't know". After several days of pain I was able to see my primary doctor who examined me and properly diagnosed. The pain had nothing to do with the pulled muscle. I was related to my IBS problems. I was proscribed the correct medication and my pain went away. I don't understand why I have to pay for the that kind of service from the Patient First doctor? I tried to appeal the charges, but since the claim was processed corrected, my appeal was denied. I did contact the Patient First corporate office with my complain and they said they will address it, but the was it. I ended up paint for the "service" from their "doctor" . I will never use Patient First again and do not recommend them to anyone.
