12 day cold!

Going on day 12 of a terrible cold/ sore throat/ headache/ stiff neck. I’m just miserable.

I went to the Dr and it’s not bacterial so didn’t give me antibiotics.

I’ve never had a cold linger this long I’m loosing my mind. Please any tips or help you can give me?

I’m already taking sudafed and Tylenol for the pain. Also benedryl at night to help me sleep.
