No cure so you gotta rest. Nose is stuffed so you gotta mouth breathe. Throat is dry from mouth breathing. Dry throat makes it painful to swallow. Pain keeps you from sleeping and recovering. Lack of sleep leads to worse symptoms like piercing headaches. Need to rest to get rid of the headaches. Headache and swallowing is too painful to rest properly. Lack of rest perpetuates headaches, nose congestion, dry throat, painful swallowing.
What is this BS
I find the over the counter cold meds at least handle the congestion pretty dang well. A few hot baths a day for sickness body pain/joint inflammation. I don’t get headaches so the worst part is the throat for me usually. Cough syrup or the drops are useless I find.
