Do I have case for a Medical Malpractic lawsuit?

On a return from out of town, I started having a cough. Within two days my cough got worst and I started having chest and back pains when and after I cough. I called the medical advice nurse about my symptoms and she recommended I come in to see my doctor immediately. I went to see the doctor but instead I was seen by the nurse. She gave me an asthma treatment, told be to continue taking my asthma medicine with robintussin for my cough and sent me home. Not short of a day later my symptoms got worst and I called the advice nurse again and informed her that I now have a fever. The advice nurse told me to stop taking the robintussin. She then had my doctor to call me for further information. About an hour later I had a voicemail from my doctors nurse telling me to continue taking the robintussin and drink plenty of fluids. All of my symptoms continued and I did not feel better. I called the advice nurse again the next day and was sent to urgent care where I was told I have pneumonia.
