I ended up with nasty RSI in both wrists from picking up DD and holding her in certain ways. Having extra stretchy ligaments post-birth set it off and then it wouldn't heal because I kept having to do the same actions again and again. I ended up seeing an osteopath and she treated it with the ultrasound machine thingamy they have - I was a little dubious but it worked brilliantly! She also strapped them and showed me some ways of moving / lifting that didn't put as much strain on the affected muscles and ligaments.
Hope you get some relief very soon. xox
