Thank you I did go back to the doctor for another antibiotic and I am pleased to report that I am much better - Thank you it is a blessing to feel better
That you would still have cough, headache, congestion and night sweats twelve days after beginning treatment with a Z-pack, strongly suggests that, whatever the site of the original infection, the cause of that infection was not responsive to the antibiotic. At this time any persistent infection could be located in either your lungs or your sinuses.
You should seek medical attention, for reevaluation, without delay, today if possible. What you have described is a serious situation.
Good luck
