Hello.
Thank you for asking at HCM.
I went through your query and would like to make suggestions for you as follows:
1. Were I treating you, I would suggest you regular
montelukast and
levocetirizine. I would also suggest you to use
salbutamol inhaler on as-and-when-needed basis for asthma symptoms.
2. For
sinusitis, I would suggest you regular steam inhalation which will also help.
3. Sinusitis is a common cause of headache, but as you are having headache for last 5-6 years, I would suggest you to consult a physician to rule out other possible causes of headache. In general, I would suggest you to take
paracetamol for headache.
4. Please consult an Ophthalmologist for blurring vision as it is usually not related to asthma and allergies.
5. I would suggest you
allergy testing which will help you identify the substances causing allergies to you as well as the measures to avoid them.
6. I would also suggest you regular breathing exercises and a healthy diet rich in
vitamins and minerals (adequate green leafy vegetables, fruits, sprouts, etc) which will improve your lung capacity and immunity in a long run.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish you the best of the health.
Thank you & Regards.
