For about 9 mos. I keep getting sick with cold simptoms. Mostly slight head ach, body ach, I have alot of flem from my nose and chest, but not a runny nose. Sometimes a soar throat, and slight swelling in the neck. I am sick for 2 weeks then it goes away for 3-4 days then comes back. Then I might go 4-5 weeks the comes back.
