sulayne my guess is that you should maybe go to the doctor, you may have developed the cold but if nothing is working for you then maybe you have developed an upper respiratory or lower respiratory infection. if it is just a cough alone then i strongly suggest you go to the doctors.have you got any other symptoms that point to just a cold such as: runny nose watery eyes? if it is just a cough as i said and you have had it for more of 1-2 weeks go to the doctors if your cough sounds like a whoop or a bark then its highly recommended because you may have developed croup or whooping cough .
No. What works best for me is hot chicken broth or soup or hot tea.
