Hi,
Please try following general treatment. It is safe and medicines are easily available.
Anu Taila - 2 - 3 drops morning and evening. Can be used Sos for congested nose.
It is really effective. Try to buy from some south indian chain- Kottakal vaidya shala, arya vaidya ratnam etc.
Sitopaladi churna 1 tsp mixed with honey - 3 times a day.
Agastya haritaki 5 gms 3 times a day
Hinguashtaka churna 1 tsp before every meal

Better treatment can be given after analysis of body constitution.
Hope this helps you!
