Iv been sick over a week from RSV?

I caught a cold from my son whos 3 months old. He had RSV last week . The 3rd day he came home from the hospital I got sick. I was with him those 3 days. He has gotten better but I have not. At first it was a standard cold that got kinda nasty. I had clear snot. Congestion, runny nose and a sore throat. After a few days of that things seem to be getting better, clearing up. Iv been on benelyn sinus and cold pills. They were working. Then all of a sudden 2 days ago I have the same thing from the start.., minus the sore throat but this time my snots yellow and thick. So much of it and my jaw/teeth are aching bad ..headach too. Burning on and off around my nose and eyes. I just feel horrible. Medicine isnt working. I was told by his peditrician that rsv is a standard cold for us adults. Should I go see a doctor? Or change medicine? I dont have a fever but my cheeks on and off go really red and hot.
