What Causes Ear Pain After Micro Suction?

I recently had wax removed from my ear. I have had tympanoplasty. On previous visits a Binocular Operating Microscope was used and I was asked to lie down for the microsuction. These visits have always been successful. However, on my last visit I was sitting through the treament and a Microscope was not used. To-day my ear is hurting and my Tinnitus level has raised. Should I heve been lying down and should a Microscope have been used?
