Complications after Tympanoplasty.

Hi Doc, I had Tympanoplasty 4 months back to repair a rupture in rae drum . After some time after I was discharged , I have been sneezing a lot and a feeling of cold along with "tear of a paper" like sound whenever I gulp something (water , food , even just air ) sound in ear . Also , due to rainy season or due to some reason I had developed infection in ear twice and also now feeling stuffed like some wax has been deposited on ear drum Could you please explain "tear" sound , reason for developing infection for multiple times and the COLD like feeling (sneezing a lot ) Probably some over the counter medicines that could help in treating infection first , please ? Any advice and home remedies to counter these as highly appreciated . Thank you!
