How long to recover from Pneumonia? Still short of breath with chest pain.

Over three weeks ago I was diagnosed with Bronchial Pneumonia. I was given Zithromax for 3 days and switched to Avelox 400mg for 10 days, then given another course of Zithromax for 5 more days.  In the cours of all of this I have been to a pulmonary specialist who did bloodwork and X rays of my lungs to check for possible blood clots and see if the pneumonia was cleared up.  I was given a clean bill of health and sent home with a Advair inhaler and a heartburn medication for the chest pain.

Five days later,(last night) I was still suffering shortness of breath and a indigestion feeling and fatigue. Although it had improved very slightly, it still scared me to death why I sometimes could not get a full breath of air. So I went to the Emergency room sure I was having a heart Attack or had Angina or something dire, I was also having panic attacks thinking I might be dying. (the shortness of breath and chest ache is all I have left of my Pneumonia symptoms)

The doctor did an ECG on me, Chest Xrays and more bloodwork. She came back and said I was healthy and gave me a prescription for Vistaril, which is supposed to help me relax.
Is it normal for me to take this long to get over pneumonia? Or could I have something much more severe? I am afraid I am dying and no one will help me.

Pneumonia is a serious infection and it sometimes takes weeks to completely resolve the symptoms.  If the shortness of breath remains as a persistent problem, it is a good idea to have a lung function test (spirometry).  It is simple and will tell the physician whether to change or increase the Advair to help with the breathing problem.
