I Had Varicose Veins Stripped And Lazered. I Was Given

I had varicose veins stripped and lazered. I was given Meloxicam 7.5 mg to take once daily. I took the first one Tuesday and have had diarrhea every morning since. For the first time I had a bout tonight too. I did not take one today. I have RA and take prednisone, azathioprine, Cimzia (every 4 weeks), Sulfasalazine. I had surgery Tuesday and took Meloxicam from Tuesday through Friday. Considering all of the other anti inflammatory drugs that I take, do you think that it is necessary to continue Meloxicam considering the side effect?
Thank you
