Anti-inflammatory drugs
WLS patients are no more likely to get ulcers than non-WLS folks from NSAIDS. The issue for RNY patients, though, is the risk of ulcers in the blind stomach. You don't mention which WLS you had, but if you had RNY, or if you are particularly at risk for ulcers for some reason and want to avoid NSAIDS, the only other anti-inflammatory drug would be steroids.

Since Celebrex is an NSAID, I would not take it anyway.

You have to weigh the pros and cons of suffering with your arthritis versus risking developing an ulcer in your blind stomach. If you've previously had an ulcer, or any sort of GI bleed, then stay away from NSAIDs. (Google NSAIDs for a list of them and products that contain them.) Mobic is supposedly the NSAID that's easiest on the stomach.
You can take things like Ultram or Tylenol for the pain, but they're not going to help with the inflammation. And there's always steroids.
Depending on where your arthritis is, you might benefit from the pain patches I use. They're called Lidoderm, and they don't contain any NSAIDs, just lidocaine. I find they help me a lot of places like my knees, feet, wrists, etc.---'skinny' places where they'll tick well. They don't seem to help as much on places where there's more flesh over the joint, like my hips, and they're useless on my neck because they won't stay stuck on.
