Z pack, two shots two different antibiotics..finished them all... here are my current symptoms: nauseated, foggy head, tingly hands and feet, SHORTNESS OF BREATH when climbing my daily work stairs, yet I can walk my three miles at night with my husband. My chest feels like it has weights sitting on it at times! uggggg ..... feel like i need to eat to stop the nauseous feeling but that does not help. married for 21 years, husband had a V=NOT PREGNANT
