Had to leave work early yesterday as was nearly bent double in pain from sore stiff neck on right side and sore right shoulder. Having got my jacket off in agony I got to bed and took strong painkillers and pain subsided. Bit better today but still sore and stiff...wonder if it's something to do with my bike position!? I'm 6'1 and ride a Cannondale XL hybrid. Would go to GP but takes days if not weeks to get an appointment.
