Hi,
I've tried arthrotec for my spinal & ankle and other joint pains and achiness. Unfortunately, it did nothing for me, but that is not to say it won't help you. It's another one of the NSAIDs (anti-inflammatory) and is similar to ibuprofen. And it can cause GI and other side effects, just like other NSAIDs. Do you usually have those common side effects while taking other NSAIDS? Even if you do, it might be worth a try anyway, as not every one of these meds necessarily gives one the same side effects.
