My DS has been sick with fever, dry cough, PND. Has been to the doctor twice. Antibiotics didn't help, cough suppressant didn't work, Benadryl didn't dry up the PND. So he started using a Neti-pot yesterday, and is feeling a lot better, encouraged.Currently getting over 3 weeks of probably Covid and then 5 days of very high fever, chills, dizziness, constant headache and food tasting like sawdust. Thought it was the flu because I'm a teacher and it's going around (test was negative). After 5 days of antiviral medicine and absolutely no improvement, I went back and was diagnosed with a bad sinus infection. So I'm hopeful now and no longer wishing someone would just shoot me and put me out of my misery.
