Last night I went to bed, towards the middle of the night I strted experiencing a lot of pain in my throat, I could not sleep at all. Then I felt feverish. I woke up the next morning, my flem was near greenish yellow and was very thick. My throat still hurts not as bad as last night though. I am very congested. Every now and then I'll feel a bit feverish, I have a very very small cough almost next to nothing. I feel very weak and tired. I took 4 capsules of dayquil cough and flu through out the day. I've be in bed since around 2 pm it is now 8 pm. I had a half of a sub to eat for lung and that's it. Is there anything else I can do to overcome this ?
