I've got something that seems like the beginnings of an upper respiratory infection. Anyone know any good home remedies for this? I've tried everything I know of, plus taking some store brand mucinex, but it's not working. Actually, it started as a sore throat (which is gone now), turned into a stuffy nose and head feeling, then into sinus drainage, now it's going into my lungs. I'm worried that I may end up having to go to a doctor for this, but would like to try anything else I can first, as I really don't have the cash to spare right now. Thanks in advance.
