Part of both of my eyes have become reddish; l also have a sore throat, a cough, and a stuffy nose. The red eyes have been going on for about four or five days now, the last two symptoms for two days. l was just wondering, are the red eyes related to my cold or is it just a coincidence? My eyes have never turned red before while sick... How long will it take for the redness to go away?

hmmm could be hay fever allergy.
Happened to me once, started as an allergy then it became a cold, and l got really ill. see a Doctor if your really concerned about your health.

l usually take benadryl and have some orange juice when l get like that but being that you dont typically get the red eyes and have had that symptom for a few days l would go to the doctor just to be safe.

Hay fever does that kind of thing. It is your allergies affecting your nose, throat, eyes, it can cause dry mouth, make your throat sore, and you should probally put in some eye drops in the eyes to make them less dry.

hayfever, or maybe you have a cold and conjuncitivitis (eye infection) go to docs

It is hayfever. l always get that. it sucks. U feel horrible. But it will go away.
