Hi, Welcome to health care magic. The problemof low back can be due to many causes like osteoarthritis, rheumatoid arthritis or ankylosing spondilitis or trauma to skeletal system. The diagnosis should be made before starting any treatment. Steroids are known to increase blood pressure specially during initial periods. Naproxen is an NSAID group drug that also increases blood pressure, so it is highly advisable that you don t take the medicine by yourself but under the supervision of a qualified physician. Vimovo is to be used for short term because long term use may cause complications like heart and circulation problems and gastritis. I hope the advice will be helpful for you.
