I have had a dull headache for 4/5 days but today it’s turned into an awful migraine like headache. I feel nauseous but assuming that’s the headache. Over the past week or two I have had sciatica type pain in my lower back and down both legs and my neck has hurt. My temperature is 36 degrees. I had a thickly throat and cough a few times twice today because of that. I have no idea if this is the virus.
