Was just coughing up mucus (yellow/golden) yesterday and couldn't sleep at all last night because I had to get up every two hours to hack up mucus. Today I went to work and felt miserable - by lunch I got mucinex and it helped looosen me but by the end of the day my body was achy and my eyes and head hurt and I was running a low fever 100.2 went up to 101 by the time I got home so have been taking Tylenol.
