crazy pains on my shoulder blades, neck, especially my right side

[NLfool]

it's been on going but nothing like this. I played like 4 20 min sessions today and could barely stand it anymore. Got a massage after 2 sessions and it felt great but after 20 min on the computer again my shoulders, shoulder blades, and neck (right side) are killing me. Maybe someone here has magic remedy before I get some profess. help.
