Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms it is probably clear that you have
SINUSITIS and seems to be due to allergy and the episodes are more in winter due to cold weather causing more of congestion..
As you presently have an episode of Sinusitis I would advise you to consult an Otolarynglogist and get evaluated so that he can do a thorough evaluation and required investigations like PNS View [ x ray], blood tests, culture of phlegm for vial or bacterial infection as well as blood test for ruling out
allergic reaction..
After a confirmatory diagnosis is made he can advise you to take antibiotics like
Amoxicillin, antiallergics like
Cetrizine or Fexofenadone [allegra], decongestants like Pseudoephadrine [sudafed], steam inhalations and saline
nasal spray.
At times surgical approach is planned if medical treatment does not improve the condition for draining the sinuses and removal of any polyp or tumor in the sinus.
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
