Pictures would be useful. However, I think the fact you are thinking about this shows some awareness of what is going on in your body and that is never a bad thing. I would say, try to keep your body, as a whole, as balanced as possible. That way you will avoid straining any one part of it. Prolonged strain is what causes problems in the future. You could also look at how you use your fretting arm/hand. That is part of the balance. Awareness is the key though and you seem to have that.
