It started yesterday and I thought it was just from the hotel couch. But my back ached and everything I sat on seemed too low like I had grown a foot taller or something. Then during the afternoon my skin just randomly started hurting. Then I woke up.15 minutes ago and my left side and back hurts so badly and I can barely walk. When I lie down I feel like I'm lying on legos

Idk if this is still the couch. I've been in a mood and puking up everything for 24 hours too.
