That said I have elbow and shoulder problems some kind of inflammation.
To all guitar players with pain in your joints elbow shoulder etc...
Get off all diary products!! cheese,milk,butter, and cream etc ...you have to give it a week and you will not believe how much better you will feel and play!
I'm NOT a doctor. But it is well know that diary causes joint inflammation. You can slowly reintroduce some or have on ocassion.
Then you can get whose octaves going and practise for hours and hours.
