Thank you for the query.
I advice you to consult a ENT doctor as there may be just a sinusitis
or there must also be nasal polyps for which allergist cant do anything and again you need to go to ent surgeon for this.Take steam with karvol capsules and you need to have antibiotic treatment with amoxicillin
for 7 days.As you are also a sufferer of migraine
you are having those headaches
more severe.For this you need to take prophylactic treatment to prevent frequent attacks.Thank you.
