I have been working in the garden the last week, doing a lot of raking to sow grass. The last couple of days my shoulders are acting out. Im quite fit after doing strength training for the lest 8 months and am suprised that this is suddenly a problem. Im not sore like after a workout, it feels more like the unpleasant feeling after doing to much repetetive work. How do I know its just tms again? Thanks!
