I vote ring sling! If you can get one that really cups the shoulder you'll have no pain. I have a mei tai style carrier, a framed back pack, and have had pouches, but it's the ring sling that feels good, even with my 3, almost 4 year old. The back carry takes a bit of learning to get right, but it's so liberating! And I can still wear her on my hip or in front to nurse in the same carrier.

Nope - ring sling won't work - we abandoned that long ago with my first - I just can't seem to get it right over the un-injured right shoulder. The nature of the injury makes it worse when the shoulder is pulled forward. No amount of re-arranging can make it comfortable, beleive me, I've tried. Thanks for the suggestion though!
I had an old generation ergo and have chronic neck/shoulder problems. I figured out that the ergo was just worn out. I got a new-to-me used one that is still newer and the problems went away. Very sad to lose my older one but it had been through 4 kids and the fabric started ripping along the waistband. Oh, I also have a Storch woven wrap that I still use and love.
Just wanted to add that I find the new Ergo is better for long trips IME. The storch is fine for 3-4 hours but then my shoulders start killing me. We just did a day trip via train where DS was in the Ergo for 7-8 hours and while that wouldn't have been possible in the old one, it was fine with the new one.
