Can fibromyalgia pain be in lower back, knees, arms, wrists, hands, knuckles n elbows, both sides of body, n sleep bad. On neurotin1600mg meloxicam 7.5?

Depends. Low back pain is common in pregnancy. Depression makes all pain feel worse than it is. Coping is also more difficult when depressed. Please review your medication list with your physicians since the conditions you list are fibromyalgia, pregnancy, and depression. Previous radiation therapy and chemo can also cause some ongoing nerve pain. I hope you get sleep and your doctors safely improve this.
