Try gurgling salt water it really helps your throat cast. As for the runny nose blow it ofeb take some over the conter meds and put vicx on your chest and under your nose.
I had a really bad cold. Every night I put Vicks on my chest and my feet and put socks over them. (It works!) I also take a warm bath everyday. I take a Halls everyday just to help my throat.
Hope I could help!!
