Hello
As you describe in your query that there is watering in the eyes, running nose ,
sore throat, cough with phlegm or without phlegm, headache, back pain and also pain in the left side of chest . These symptoms sometimes recurs ( rather so many times), some relief with antibiotics . Mucus reliever , antibiotics, ibuprofen and many more medicine with no relief.
Also there is heart burn . But heart burn may be due to hyper acidity either due to medicine used for these symptoms or due to these symptoms.
These symptoms may be due to Asthmatic allergic
bronchitis . When patient get some allergy there develop
bronchoconstriction and this bronchoconstriction causes breathlessness and cough , while allergy also causes tears from eyes , itching , blocking in nose ( also
post nasal discharge ) .
Some times this allergy when combine ( super added ) with infection there develop pain in throat , headache ,
neck pain .
Dust , mite , pollen , hay , fodder , fine dusting powder , sudden fall & rise of temperature , humidity are predisposing factors of these symptoms i.e. allergy.
Avoidance ( from these factors ) will help.
When such patient visit I usually prescribe them monteleukast+ bambuterol ( combo pack) once or twice in day till complete relief.
If sore throat I advise them to take
levofloxacin 750 mg / day for 5 days .
Since these drugs are prescription medicine so get a prescription from a doctor .
Hot coffee also help . If blocking of nose very severe you may need some
nasal spray.
Hope this information will help you.
Good luck.
