Hello and welcome to HCM,
The problems that you are facing - nasal blockage and
sneezing due to
allergic rhinitis have to be treated.
Allergic rhinitis is a seasonal allergic phenomenon in majority of cases.
Allergy is commonly against dust, mite, pollen, dander, etc.
Avoiding these agents is the best measure against allergy.
However, it may not be always possible.
Anti-histaminics are a group of drugs which relieve these symptoms.
You can get them prescribed from your doctor.
The
dark circles may not be caused by sneezing and nasal blockage.
However, the fomites can affect the skin.
Take good sleep of 7-8 hours daily.
External application of creams may not help.
Thanks and take care
Dr Shailja P Wahal
