As we have discussed, I also have PsA, and though I have not as yet used Mobic, I have taken NSAIDS for a decade on a regular basis, Daypro being the longest.
I had been taking 1800 mg daily until my Rheum told me that it was too much, over the daily limit. He explained the reason that prescription and OTC NSAIDS require a daily recommended dosage that needs to be closely followed. The reason was possible damage to liver and kidneys if taken in large amounts, and lets not forget the stomach. He went on to tell me that this was the main reason for regular fasting blood work. He feels it is best to go to a narcotic rather than over the daily limit on the NSAID, when greater relief is required.
My first BF group and first moderating position was on Psoriatic Arthritis, and there I learned the phrase, "fear the disease, not the drug", as every single new member had more fear of medicine than of the disease itself. In my opinion, as a patient, we need these meds to slow progression, inflammation and degeneration, especially of joints.
I fully realize that not everyone can tolerate meds, and in these instances I feel it is always wise to find a qualified, highly educated alternative Physician to prescribe these alternatives for the best, safest care possible, as the effects of these also need to be watched.
I truly do understand your concern about these meds, however, your Physician will closely monitor you, and of course you will always report any possible side effects, so unless you are having problems with a certain med, the value it has in reducing pain and inflammation are tough to replace by any other means.
Sometimes people kid themselves thinking that using herbs or something considered 'natural' would be better, but unless you are under the direct care of a master herbalist or nautropath, you can cause yourself more problems than you may think.
Sorry, didn't mean to get on the soapbox with you! Really! Just wanted to get that out there!
Hope the Mobic gives you some relief. There are many on the PsA, Lupus, and Fibromyalgia sites of BF who take this med, so it must be a good one!
Wishing you well,
