Just wondering where exactly the pain is? Do you get shooting pain at all, any other pains at all?

I suffered with lower back pain for months and months and finally 6 months after birth I couldn't deal any more and went and saw a physio. 2 months of weekly sessions and I haven't been back and haven't had any back pain either. It was just a matter of adjusting the way I did things (posture mainly) and also for my body to rid of the hormone relaxin. I was diagnosed with sacriotic joint dysfunction.

It might be worth seeing a physio (most hospitals offer them post birth for a period of time) but first I'd look at things like posture and the way you are wearing bub. Try and equal out the weight if you can.

Hope that helps x

*ETA* Oh and keep doing your pelvic floor exercises, they should help with some lower back pain!
