Yesterday morning my left elbow felt awkward when I woke up. I'm pretty sure I slept on it in a weird way because I remember waking in the night and turning onto my stomach, which isn't a usual sleeping position for me.
My elbow looks slightly swollen on the inner side, though nothing really obvious and certain movements are still hurting. I can't comfortably bring my arm up to my shoulder close to my body, or stretch the arm out really straight. The outer side of my elbow is fine. It feels like I've stretched a tendon or something on the inner elbow. Almost like I overstretched doing something physical- but I know I didn't do that!
Any ideas?
