so is piroxicam (Feldene), along with naproxen (Naprosyn), indomethacin (Indocin), ketoralac (Toradol), meloxicam (Mobic), and I'm sure there are others I'm not so familiar with.
BEG, if you aren't around loud noises, can hear fairly normally except for the tinnitus, and have no other complaints about hearing difficulties, I would most likely chalk it up to a side effect. That doesn't mean you should just quit taking your meds, talk to your doc first.
