For about 5-6 days I've gotten a few cold symptoms like I never have a clear nose, it is either really stuffy or really runny, I dry-cough a lot but my throat has a lot of phlegm, and I sneeze very often and I'm not sure if this is relevant but two days ago I woke up so weak I could not stand up on my legs without shaking and fearing I'd fall. I have no allergies to any foods, pollens, or dust. And for the record I don't get colds very often, but when I do, they go away in 3 days tops. Should I be worried? Or is this just a long lasting cold I'm overreacting about?
FYI yes, I've been drinking lots of water.
Appreciate all replies. I apologize if I do not post a response back quickly.
