I have had a persistent dry cough for 10 days. I saw my GP and he said I have a cough/virus and wait 7-10 days. It's not getting better. Thoughts?

Mgt: Some viral infections are associated with prolonged cough and wheezing/bronchospasm. I would suggest inquiring about this possible cause. If you have symptoms of a bacterial infection, a secondary infection is also possible. If you should spike a fever, then a chest radiograph can be obtained. ...Read more

I took Robitussin (guaifenesin) for a persistent dry cough, no luck so i just took nyquil two hours later is that ok?

Yes: As long as it was plain robitussin, that's fine. If it was Robitussin dm, (guaifenesin and dextromethorphan) then you would want to wait at least 4 hours in between the two, because both of those have a cough suppressant in them, and you don't want to double up on the same medication. ...Read more

How long should I wait to go to the doctor with a persistent dry cough, sore throat, and low grade fever? It's been about a week.

How long should I wait to go to the doctor with a persistent dry cough, sore throat, and low grade fever? It's been about a week.

It depends...: I think this depends on what type of doctor. From your symptoms the odds are very high that this is a viral infection. Research studies show that antibiotics are likely to do more harm than good. However, herbs, homeopathic medicines and acupuncture may help so if your Dr. offers these it would help to go. I advise trying Umcka, available at health food stores. See http://tinyurl.com/ztoepsy ...Read more
