Do I have the flu or worse?

I have really bad allergies this time of year. But take medicine for it. The past week, I have been coughing, sneezing, stuffed up, feel like i have hard plegm in my chest. Don't have a fever, but achy, I have siatica(think thats how its spelled) My neighnor and 2 of my friends I hang out with now have bronchitis. Last week my phlegm was brown now its border line clear. I'm having problems breathing, Havent had a cig in 2 weeks. Regardless, Im heading to the ER tomorrow without insurance woohoo.
