I woke up yesterday morning with my shoulder and neck very sore like I'd slept on it wrong or something. Usually, it gets better as the day goes on, and it seemed to do just that until last night. About 7:30 last night, the pain got exceedingly worse. I took some Aleve, then a muscle relaxer, and neither helped. I ended up going to bed early with a heating pad. I hope it will be better today and a good night's sleep will help it.
