Etoricoxib and celecoxib pain relief advice

Hi there I’m new to this group and really need some advice. I have psoriatic arthritis which is extremely painful. I’ve been prescribed etoricoxib which I had every side affect so had to stop taking them but now I’m on celecoxib and still having minor side affects but the pain is still really bad and really getting me down. Are there any other pain medication I can take instead of or with the celecoxib? I’m at a bit of a loss as to what to do. Thanks so much Lauren x
