Pleurisy

I neglected to mention the latest medical issue in our house...Catherine has pleurisy.  About five weeks ago she came home from a chilly band competition and mentioned that her friends had talked her into leaving her jacket on the bus.  Sure enough, she developed quite a cold.  Nothing that made her miss school, but enough to not feel great.  Her cough went away, then returned.  It's never been deep, but when she does cough, it's pretty strong and continuous.  Early last week, she mentioned that her side hurt right around the rib cage.  She came home from swim practice last Monday nearly in tears from the pain.  I suspected pleurisy, and after taking her to the doctor last Wednesday, it was confirmed.  He put her on an antibiotic, and although she does still have the cough, it has gotten better.  She feels today that the pain is better as well, although she tried to return to the pool Monday, and that went so poorly that she now is not allowed back until next Monday.  Of course being the anxious parent I am, I become terrified that something is seriously wrong, but hopefully it was just an upper respiratory infection, and all will be well soon!
