hi i am a black male aged 41, i weigh 109kg at the moment.i have enjoyed fairly good health until my recent cold which has persisted for more than 3 weeks.  about three weeks ago i got a sore throat which turned into a fully blown cold with blocked nose, productive phelgm from my throat. i was treated with augmentin for about a week and the cold slowly improved but has not completely disappeared.i am still experiencing the symptoms as in my nose is still blocked and producing mucus. we have been having some unusually cold weather at the moment in nairobi and my kids have also been sick as well. what could this be?
Brief answer it could be a hypersensitivity of upper respiratory tract to cold. Detailed answer have gone through your query I think I have a better answer to help you outing my opinion it could be because of hypersensitivity of upper respiratory tract to cold since you had a full course of antibiotics (augmenting) still having the similar symptoms and that also runs in family would advise you to take Fluticasone or Elastane nasal spray to be taken twice daily with steam inhalation and avoidance of exposure to Chat Doctor.  If you have any further questions I will be happy to help wish you good health
