i was walking my dog, and she tripped me, and i fell, face first into the sidewalk. i m developing a big goose egg above my eye, it s scraped, about 3 inches wide, about 1 inch tall. i m concerned about a concussion, and i live alone, so there s no one to watch me. is it safe for me to go to sleep? i was planning to come home, feed her and go to bed. i also have a cut on my cheek, but i m not as concerned about that.
