sunutab are very good. Unfortunately, i've tried the cheaper alternative, and the weren't as effective.
The last time i was suffering, the doctor gave me a nasal spray called beclometasone. it was for hay fever but did help.
I suffer from sinusitis a lot, but have to say that it doesn't give me the ear thing that you describe. The only time i had problem with my ears with it, it turned out i had labirynthitis, a totally different inner ear condition. Perhaps a trip to the doc would be in order?
