Yes. Or no.
As you may have guessed by now, a broadly phrased question is going to get a broad range of answers. For more specific answers you'll need to narrow your question and its parameters.
What sort of bike do you ride?
What is the nature of your rides and how do you ride them?
What sort of bar do you have now ("Flat" comes in many variations)?
What is uncomfortable for you now and how long does it take before discomfort sets in?
What else works or doesn't work about your current bike's setup?
Do you have any physical impediments or limitations?
What about your strength and flexibility?
Some more information along those lines will get you some specific suggestions. Meanwhile, the answer remains, yes, or no.
