I am from Russia.I've been here for 3 years ,never been seriously sick and did not need a doctor.I am sick now and I am confused about medications and treatments in this country.I have had severe cough and sinus congestion for 4-5 days; which is worse at night,I took oral decongestant psedoephedrine with guaifenesin and I could not sleep two nights in a row, it kept me awake. I do not know if I should go to a doctor and spend money( as I do not have medical insurance,and it's expensive for me.), or should I continue to use over the counter medications and wait until it disappears by itself or I am afraid it might get worse. I can't miss work, I work on low hourly wages and I have to go to work no matter what.So I suffer.How do I know if my case is bacterial or viral? I have multiple symptoms -persistent cough I feel it in chest,stuffed nose with yellow liquid, and I had earache last night which got a little better today.I don't know if I have fever (I don't have any thermometer at home so I didn't measure it, it's hard to tell). Do I really need antibiotic(that means I have to go to the doctor and get a prescription)?,or should I endure all that if it's viral they say antibiotic does not help anyway,or can it be the combination of both viral and bacterial infection? How does the doctor know if the couse is viral or bacterial ,how do they make the desision if I need antibiotic or not? How can I get better without spending much money? What should I do ?
