Symptoms: Sputum

Doctor: Hi.Thanks for your query and an elucidate history.The excessive production after you football is an indication tha t there is something in the ground that is causing you an allergy, producing excessive sputum.The strange smelly sputum bits of greenish color is just an infection. This can be just a part of it or could have come from the nose or sinuses.If there is repetition, you send the specimen to the laboratory for gram staining, culture and sensitivity.You may need an antibiotic if the problem persists.The basic rule is to avoid the allergens; you have to find the cause and try to avoid it.Or the else you may have to take antihistamines and continue with life.I hope this answer helps you.
