Been in a house with an individual whose positive for covid. I’m on day 8 of being quarantined and doing good cleaning and staying away, but yesterday I started to have a tickle in my throat that made me cough and a constant minor headache. Now tonight the cough is still a tickle but the cough is a little deeper.. and my temp was 99.4 at the highest… I took a Tylenol and the temp is 98 now. Headache gone. I had the J&amp;J vaccine but I’m worried it’s covid.
