Hi...I was misdiagnosed by my MD and put on Naproxen for Rheumatoid Arthritis. The Rheumatologist  says I dont have Rheumatoid Arthritis but asked if I suffered from high blood pressure or chest pains. No! My blood pressure is usually around 117-123/ 72-80. But I told him I have been having chest pains and palpatations, so he send me right away for heart ultra sound.  He said to stop the Naproxen immediately. So Ive been talking the wrong med, for the wrong diagnosis! My question is
Hello to Chat Doctor, NSAIDs (Naproxen) are one of the most widely used Chat Doctor.  They come with their side effects, unfortunately one of them is High blood pressure, due to the fact that these medications lead to retaining of body fluids and thus elevating the blood pressure. So after you stop Naproxen your BP will be lowered in no more than a week. On the other hand you should be very careful and try to get to the bottom of your case because RA is serious disease.
