Heaviness in ears. It be taken care of.

Around a month back, I had severe pain in my left ear. I showed it to an ENT specialist and got wax removed. Also I got some medicines prescribed to me for a month. Medicines were Protal SR 40 mg, Nukast 10 mg and a nasal spray Floresp. I was told that my ears were fine. Nose bone is tilted a little. And throat has sign of tonsils. Hence, I was given this medication. Now I have a history of migraine, however, the last one month when I was on this medication, I didn't get headache even once. But after medication is over, I have again started feeling heavy in my ears, little irritation in my nose and I have been getting headache for 3 days continuously now. I need to know what exactly is causing this and how can it be taken care of.
