rheumatoid arthritis
"I started taking Aleve for my Arthritis in my hand and the pain was gone but after taking it for about 8 days I noticed swelling in my feet, which was abnormal for me. I am 34 and in good health and have never had swollen feet. I then noticed the next day my feet and hands were swollen. I finally put 2 and 2 together and realized I was allergic to the Aleve. I stopped taking it and haven't had swelling since."
