I have similar symptoms as many others. After two weeks I Saw my doctor. The first four days I had a severe cold with a feaver of 100. Sinus headache and post nasal drip with a cough.When the cold subsided, I still had tightness in my sinus area and headache. My feaver comes and goes and remains around 99.4. Blood tests were taken and a chest xray with normal results. I felt better for a day and a half then got worse. Went back to the doctor with new symptoms of ear, neck and tongue discomfort a week later. I have spent all this time in bed with fatigue. The doctor put me on amoxicillin as there were signs of an infection in my throat. Since my temp is up and down, am I still contagious? There are no cold symptoms and my neck, ear throat and tongue are symptom free.
It looks like no one in the medical industry is going to answer you. I hope you're still alive and doing better.
