My LO is a little high maintenance and nurses pretty much every hour. For my survival, we co-sleep and I nurse him in a side-lying position at night. We both fell asleep the night before last and ever since I've had an awful crick or knot in my right shoulder and the right side of my neck. Has anyone else done this? Is there anything I can try to help it? I've been applying moist heat packs, but geez it hurts!
