Lack of sleep

I’m exhausted today. My neck muscles at night are tightening up so much it’s sore to lie on a pillow if I lie with my head to the side I get some relief then it starts pulling my muscles into my collar bone. My knees are the same ok if I lie with them straight but when I bend my knee I wake up in pain during the night. I have a massage once a week and she helps slacken my muscles she has been ill this week so wondering if that’s why everything has just continued to tighten. I’m on 60mg of baclofen as it is. Neuro says I’m not tight but i am. I can’t go on like this
