I had total hip replacement on 12/12. I was put on Celebrex and then aspirin. One week after surgery I developed generalized itching and then an increasing deep blistered rash on my back and front torso. I also developed gastritis around 3 weeks post-op. I then went off all NSAIDS, taking Omneprazole. My question is about this rash, which is still very bothersome itch wise and the lesions are very deep and slow to heal. My neighbor had this same skin reaction after taking Celebrex! I wonder how long I should expect this rash to last?
