28 week appt w/ back pain and he is breech

Tina

This is my 3rd pregnancy and I never had back pain like this before. Lower back pain that kills me when I stand and walk. Trying to still keep walking every day and using a heating pad but wondering if anyone has any other tips to relieve the pain. Also baby boy was measuring at 3lbs 5oz (70th percentile) at 28w 2d and he is also breech. Dr says not to worry he will flip so I am trying to stop thinking about it. Any one else having these problems issues?
