I've been fighting a really bad head cold since last Fri. I've been using my Neti pot, steam, vaporizer, hot compresses, and used Afrin for two days. It's better, but still not great. I'm still breathing through my mouth for the most part. TMI, my mucous is still clear but getting thicker and it's started going to my chest. I've been have a very loose cough for the last two days. I think I'm going to try some Robitussin, but at what point to I just go to the dr? I don't want to take an antibiotic I don't need, but at the same time I don't want this turning into bronchitis. I have a checkup with my OB on Friday but I don't know if she'll write me something for this or tell me to go to my PCP because they explicitly state to call your PCP when you are sick, not them. Should I let this go a few more days and see what happens?
