i have no way of determining over the internet based solely on your symptoms if you have a cold or "something else". this requires a hands-on medical examination and a more thorough medical history. antibiotics have absolutely no effect on colds which are viral. unless you have a secondary bacterial infection (bacterial sinusitis bacterial pneumonia etc. ) antibiotics are not needed or helpful. people with asthma are more prone to secondary infections and since there are over 200 different viral strains known to cause colds once can certainly get back-to-back different viral infections all having a similar array of symptoms. this often happens during the fall-winter months -- the cold season.
i have had a cold for the last 3 weeks is it really a cold or is it something else? . cough (varies from non productive to productive). nasal congestion. headache. i have already been on antibiotics. i do have asthma.
