Totally felled today by neck spasms down right side.

hoping it's totally unconnected from any acoustic practice. [br]5 months into playing electric but only a couple of months playing acoustic. [br]very aware that as a beginner I tend to crouch to see frets and hand. [br]Tried off both legs and using a low footstool. [br]Yesterday felt fine , off left leg, trying to sit much more upright, head high and square across the shoulders.[br]see more posts about hands, fingers and shoulders rather than the neck. [br]Now looking at guitar lifts, supports off the leg to set the neck angle allowing the player to have 2 feet on the floor nice and square. [br]What is the experience of others who have tried thes devices. [br]No practice for me for the next couple of days.
