I slept on my couch in an uncomfortable way and I really felt it in the morning. My left shoulder and spine hurts with about every movement I make or if I hold up things like a cup in my left hand. What can I do to treat myself as quickly as possible? I feel helpless so I've just been distracting myself by playing some Pokémon Brilliant Diamond, but I'm afraid I'm going to have this pain for a week. Are there exercises I should try or food I should eat? Any help would be greatly appreciated!
