What is wrong with me, I catch colds, flues very easy and cold lasts a month and flu even longer. Always starts with stuffed nose, sneezing and totally stuffed head with sinus pressure that makes me feel like I can only breathe thru my mouth. After a week or two from the onset all stuff drips down to my throat and lower, that almost always ends with bronchitis lasting for few weeks. I am very week for few weeks and my body is a wreck after each epizode and takes me few more weeks to recover. Please help ,I am loosing a lot of my lifetime as I go thru this since I was a child.
