I've had cold with mucus for the last 6 weeks,, it goes away then comes back with vengeance it started again last night after being free from it for 7 days. had chest xray with first bout, xray showed nothing The Dr on duty wrote me a prescription for Sudafed which I did not fill! I know sinus/allergy and that is not what I have ! This time its different there is very little mucus just a horrible "bark like" cough,, my chests hurts and now I'm experiencing chills, headache . I have had bronchial issues since childhood , thus whenever I get a cold it typically goes to bronchitis.. The coughing sounds like whooping cough when I am unable to catch my breath . I am 71 years old,, no health issues ,take no meds . I'm thinking I need antibiotics , Are your Dr's able to write prescriptions online? If nt it is pf no use to me to pay the $$ Thanks Judith
