Pain

My body aches...seriously. Every joint. Neck, shoulders, elbows, wrists, fingers, knees, toes, lower back...even my ribs feel sore. I went swimming this afternoon and had sharp elbow pain every stroke. My left ear is terrible. Cartilage pops with little pressure and I can't lay that side of my head on a pillow. Odd...today was my 3rd day off after 4 consecutive training days. Why do I hurt so bad now? I'm 34...but feel like 60.
