I get some wrist pain, because the stock bars do not give me a neutral wrist position. It usually takes a good 8-10 miles for any kind of pain to kick in tho, so I haven't done anything. Yet. I'm still debating about going to a mustache/north road type bar. The Ergon grips cost about the same, and won't get me to a neutral position, but will reduce pressure on one set of nerves. It's more an upgrade to cut down on breaks for long rides, so it's just not a big priority.

I've never had *elbow* pain on a bike. That sounds kind of weird to me, and leads me to think that your problem might not be very similar to mine.

I have had upper arm pain... Electra Townies/Amsterdams have a wide riser bar, and the shop just couldn't get the bar down low enough for me on my test rides. It's also much too wide for me, so it was quite uncomfortable.

I've also had back pain from handlebars. My mountain bike had bars that were a bit too low and too far forward for me, so the area in between my shoulder blades would hurt on long rides.
