I've had lessons, and he really helped with my technique, which I think is pretty much ok (EDIT: it is now anyway, wasn't before!), and I've seen physios and specialists in the past, especially following a wrist injury in about 2009-2010. I think most of the issue with my hands is my day job, it's very keyboard/mouse heavy, but I love my job so I'm not willing to change that.
I'm not a good bassist so a video might be embarrassing haha, but I'll see what I can do

I had some RSI in my right forearm some years back, when I was using Excel a lot. I worked out that it was because I was using my right arm far more than the left - number keys, mouse, etc. I taught myself to use the mouse left handed and it helped a lot. It's a bit of a brain scramble at first, but you soon get the hang of it.
