Hi, I gotthe cold flu about a month ago, starting feeling better after a week. went to the DR. after two weeks of still lingering, sore throat, drainage and vertigo. Dr. gave me a 7 day run of Anti s. starting feeling better symptom wise, then the after scipt ended same symptoms. Dr. put me on Z-pac, 3rd day same symptoms... I am at about 30 days of this and frustrated and worried...
