Finished zpack tues. Cough is still bad. No voice but lungs are clear. Feel lousy. Dr said viral. It's been a week. When would I expect to be better?

A few more days: As your doctor told you, most infections like this are due to viruses -- and no virus responds to any antibiotic. So it isn't surprising that azithromycin (Z-pak) made no difference. Symptoms like this usually last 10-14 days. It's good your lungs are clear; your voice should return and your cough start improving soon. Recheck with your doctor if not better in a few more days. ...Read more

My son has a cold, we went to the doctor and they said it is viral so we should treat the symptoms. What are some remedies for cough and congestion?

Cold: I don't recommend over-the-counter cough and cold remedies for this age group. Humidifiers, extra long bath-time, saline nose drops and nasal suction (the Nose Frieda works wonders) are helpful. An essential oil like Thieves has been helpful but you have to really be careful with oils. Since over age 1, Zarbees (or honey with cooled chamomile tea and a little lemon could help). ...Read more

I have a hard cough after 7 days of battling viral pharyngitis. I wake with dry bloody snot when I blow my nose and pain in my chest from coughing all?

Get evaluated.: Assuming this was viral from the get-go, you should be better by now. Viral infections generally will last 3-5 days; you’re still so sick after 7 days, so there’s a better chance that something else is going on that may benefit from treatment. You need to be evaluated at this point. ...Read more

5 month Baby boy has fortnight back viral cough and cold. He was given taxim o and timnic. He is now recovering. Mother has got cough. Please advisei?

Improving...: Although you stated that the cough was viral, it seems the baby was treated with antibiotics? Either way, you mention that the baby is recovering --- so I gather that means improving. Cough can linger for a few weeks - con't with supportive care - saline drops, humidifier. It isn't surprising if mom caught the cold - symptomatic care for her and seek medical care if either mom/baby worsen. ...Read more

I have dull pain/soreness upper left chest area over the breast. Discomfort if I cough. Had a bad viral cough for 1-1/2 weeks but it was better 3 days?

Costochondritis: It's quite likely that you've sustained a 'musculoskeletal' injury from coughing. This could cause the symptoms you describe-and if you press on the area, I suspect it would hurt more. Any pain in the left chest of course raises the possibility of heart trouble -but it seems you are relatively young and female (2 things that count in your favor regarding heart disease). If the pain is bad, see MD. ...Read more
