Hello and Welcome to MedHelp,
I beleive your question is like asking, "What is stronger Aspirin or Ibuprofen?" It depends on what works best for you. They function basically the same when taken in comparable strengths.
I would try them separately, do not take them together or even close to one another and try to determine which one works best for you. Take care, Tuck
I agree with Tuck I have taken both and have found that each works differently for me for different kinds of pain. I think you just need to try both and see which one helps you the most. Good luck and feel better!!
