Detailed Answer:
Hello XXXXXXX
Welcome to Healthcare Magic.
From the symptoms you describe - recurrent colds, sneezing, runny nose, nasal blockage, headache likely
sinusitis, cough - it is likely you suffer from allergies, and the commonest type is house dust mite/cockroach allergy in India.
You may have multiple allergies, i.e., to grass and tree pollens, depending on how long you have these symptoms.
Initially there may be a seasonal pattern, but soon the symptoms happen daily it is called perennial
rhinitis or rhinosinusitis.
The following tests are recommended:
Complete hemogram
Biochemical profile
IgE levels
Allergy aeroallergen profile, TSH, Vit D3 levels, IgA levels
& Pulmonary function tests
A combination of long acting antihistamines, Nasonex
nasal spray and correct choice of inhalers with
Montelukast at night is the optial medical therapy.
Immunotherapy can be considered only after the allergen profile is available.
Best Wishes.
