Likely got secondary infection during flu
I am in mid 20s. Today is my 7th day. I still have fever and congestion.
For last 2 days, my fever have been quite better around 99.4-99.6 without fever medication after days of 100-101 fever. Unfortunately, I have again developed fever above 100 mark. Also the cough and runny nose is still there. Sometimes I get dizzy during walks. My behaviour has become rude and mean too.
My bad habits likely caused this. I used to walk 25 minutes every morning for groceries as I had no other chance. This would have strained my immune system. I also had a wrong habit of drinking less water as well as not drinking warm fluids. Also my immunity is weak due to stress from failures in life.
My secondary infection isn't confirmed by doctor but it's 100% likely. Symptoms don't worsen after a week. Now I am even afraid to tell my doctor as I am responsible for this.
