Hello.
Thank you for asking at HCM.
I went through your history. I conclude that you are having recurrent episodes of cold and cough for last 3 years and breathlessness for last 6 months, more in winters.
Were I treating you, I would consider allergic disorder and would suggest you to take daily levocetirizine, montelukast and an inhaled
corticosteroids. I also would suggest you regular nasal saline spray 3-4 times a day and steam inhalation.
All these medicines control your symptoms but they do not "cure" the allergic disease. Hence I would suggest you to consult an Allergist-Immunolgist who will advise you allergy testing and may advise
allergen immunotherapy based on results of allergy testing. Allergen immunotherapy will improve your immune system to reduce allergy symptoms. Allergy testing will also help you identify the substances you should avoid.
I would also suggest you regular breathing exercises, Yoga & Pranayama, which will help you in a long run and improve your lung capacity. Also, please try to avoid dusts, smokes & air pollution as much as possible.
Eosinophilia is not a disease. It is a finding in
complete blood count testing. It may be due to allergic disorders but there are other causes like parasitic infections, some drugs, and others.
If you have insomnia due to
nasal obstruction, treatment of
allergic rhinitis will help it. Also, both allergies and insomnia are aggravated by mental stress, so if stress is a factor for you, please try to manage it with meditation & relaxation. Otherwise I would suggest you to
consult a Neurologist for insomnia and a
Dermatologist for skin changes.
Hope this will be helpful to you.
Wish you the best of the health.
Regards.
