My right shoulder hurts - what can I do?

I'm not sure if this goes in technique or not, but if it does, please feel free to move it, I won't take it personally

Lately my right shoulder has been killing me. I don't do heavy lifting or anything funky like that, but it's just starting to hurt. I think it's coming from my bass playing.

Mostly I play sitting down, with my bass sitting in my lap. It doesn't feel uncomfortable at all for me and the bass is at a nice, even height. But could I be doing some damage to it?

Here is an image of my position while playing:


A friend of mine is doing massage therapy training so I was thinking of asking him to try working on it, but I don't want to put myself back in the same position a few months down the road.

Typically, I play about an hour a day, sometimes two, though I've been known to have three or four hour spurts, or sometimes three or four one-hour sessions throughout the course of a day.

 

Do you mean I should rest it with the curve on my left leg instead of my right?

I will try to keep it more perpendicular, but right now it's resting on my right leg which seems to be the most natural position, but I can definitely try moving it around.

 

Yeah that's my practice chair

Sounds like that's the problem then! That's good because I'm moving in 2 weeks and won't be forced to sit in the chair anymore.

Thank you

 

of course it is

if i was bleeding or something of course I wouldn't bother witht he internet, but in most cases it never hurts to ask

besides, it's a musical injury and i asked in the musician's forum. not like i posted in GBS or FYAD
