I prefer the old fashioned pills, they store better. I consume lots of NSAIDs due to my back problems. I’ve started using naproxen, because it’s stronger than ibuprofen and lasts longer, but it’s not very gentle on the stomach.
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.
