Hello Sir, I Am 34 Yrs Old. Since I Had

hello sir,
i am 34 yrs old. since i had perforation in my left eardrum, i was suggested for surgery.
My tympanoplasty + mastoidectomy surgery done in Nov-2016 and as per Dr. guidance my ear was cleaned in last week. but even now i feel rarely blocking sensations during travelling , in AC-room etc.

my question is though its 2 months over, is the sensation common or any parallel issues are there?. previously i thought may be time taking for adjusting after operation, but dr. telling not to take risk, come and meet her. need SECOND OPINION.
