Thanks for writing to H.C.M. for your query.
I have gone through your query regarding sinus problum and subsequentaly developed sore throat
, headache. You are confussed as these may be due to side effect of Flonase
Considering developmental history of your symptoms I am suspecting that you are having most likely Sinusitis
with Laryngopharyngitis. You may continue your flonase and please add these medications with due concent of your treating doctor-
(a) Antibiotic.- Preferably according to C/S report of throat swab.
(b) Anti inflammatory.
(c) Anti allergic & decongestant.
(d) Steam inhalation.
I hope this treatment will help you.
