I've been taking celebrex for about 9 months and am having very good results with it. I take it for swelling in my foot caused by Tarsal Tunnel Syndrome. My question would be how long is too long to take this medications. I understand it can affect the stomach after long term use. I am experiencing weight gain and a strange feeling in my stomach or gall bladder areas. Tell me your experiences with the medication, (good or bad). I don't know anyone who takes this same drug, that I might compare notes with. Thanks for your input.
