Hi, my lower belly and lower back hurt at times, mostly when I am in bed, and if I breathe in deeply they hurt worse. I feel like my tummy is tense and tight and its miserable. Keeps me from sleeping. Sometimes hurts bad when I roll over so I have to keep adjusting my sleep position . I am awake now and its still hurting the same but tends to go away during the day, come back when I lay down at night..
