I've seen my doctor twice over the course of the last 10 days. I had a sinus infection, which was treated with 1000cc amoccacylin (spel) three times daily. I developed a headache and cough just about mid sternum. I thought that my cough was brought on by the drugs clearing up my sinuses, post nasal drip. While my sinus infection seems to have cleared, I still have the cough, which causes the headache. Yesterday, I had chest x rays to rule out pneumonia, and was given an inhaler. I am not prone to being cold, but have been hot and cold in the span of minutes.
