Re: Chronic Back Pain..
I believe most doctors do not allow aspirin or motrin when you become pregnant so you might want to check that out. Maybe an antidepressent ?
Instead of meds, you could try:
*biofreeze/caspician creme/ben gay/icy hot (check to make sure all ingredients are okay for pregnant women)
*physical therapy - stretching
*practice good posture
*watch pregnancy weight gain overall
*natural herbs - talk to your doctor
Hope this helps
