I had experienced sinus drainage for 2 days after going to an event and was cold in the joint went to bed woke up with a fever and a burning when I tried to clear thoart did not have a cough no aches. just scary with the deep burning Went to the Dr said I had type B flu did not prescribe any meds took my own meds after fever broke feel better still trying to get the sinus drainage up some but not a lot. I wonder if I have the flu at all He did a swab but when came back into room said he did not say it was positive said I think what we have here is Type B flu said to drink plenty of fluids I feel better today after last night
