I have lumbar back pain what can I do to make the pain stop? I also have cervical neck pain from degenerative?

disks in my neck. I am having a really hard time sleeping I wake up in pain but don't want to ask my obgyn for pain pills because I don't want to make a big deal out of this. I am 4 1/2 months pregnant and don't want to do anything that will harm the baby. What do you think I should do about this because otc meds don't work?
