How Can sinus Drainage Along With Ear Pain Be Treated?

Husband has been suffering with sinus drainage,ear aches, and gagging on some foods like bread,cheese,noodles. Had been to the Dr twice and no chest congestion or ear infections.also flem is always clear. If he blows his nose hard it will sometimes bleed but the ear will open up. This is lingering and he is getting frustrated. He is diabetic and had congestive heart failure years ago and had a reaction to metformin and ibuprofen. Dr says it will clear up in time but he is frustrated. Can you give him any helpful info? He s starting to drive me nuts!
