Hi recently I met a ent specialist he told me that by seeing my Pns scan ur sinus was totally blocked and it is difficult to remove by medicine so suggested to go for operation and I'm getting severe one side headache from last 7-8years. Nowadays weekly 3-4days I'll be getting headaches. I have short term memory loss also is this due to sinusitis . So by undergoing surgery will my problem will be solved and is there any side-effects after surgery ( any swelling of nose or any other) now he given me spiromontfa tablet for 20 days and xylomist drops for nose . Now tablet also almost going to complete so what's ur suggestion shall I go for operation or not.
