Hi any advice would be great. I have a 10 month old and suffered with occasional back ache here and there but not nothing I can't deal with. Over the past 2 weeks it seems to have gotten worse! It's all across the top of my back but shifts around. One day it hurts more on the top right sometimes it's more on the left side. I have also had the tops of my arms aching over the past few days could this all be to do with carrying little one a round. He is a 23lb boy!
