I guess we go through them too fast for storage to matter. I can’t take narproxen because of my stomach. I do use a tens unit when the pain gets too bad. I also have a heated mattress pad which helps me quite a bit.
I often take a Pepsid AC and antacids a few minutes before taking naproxen.
How difficult is it to learn how to set up a TENS unit? Does it require a prescription?
