Hello, I am an 18 year old male. For the past 5 months I have gotten a cold about every 3 weeks. Symptoms include severe headache, slight fever, thick brown mucous even with blood in it sometimes, congestion, nasty sounding cough, fatigue, and a bad sore throat. And most days I have diarrhea in the morning. It lasts about a week and then comes back again like clockwork. I take multi-vitamins every day, I am active outside, and take a gram of vitamin C every morning. Also, this one is strange but my left ear feels like it has water in it, it makes that sound and feeling of water moving around in there. That ear also bled every time I cleaned it in the morning for the past year or so. There is never any pain, just bright red blood, almost neon looking. My doctor says I am fine and says I don't need any medicine the few times I have gone in, it will go away on its own she says. She checks my ears and says there is nothing wrong. Thanks for the help!
