If its in your butt cheek it is your sciatic nerve and it can travel down the back of your leg also.
I agree the baby is probably laying on a nerve.hopefully your lo will move and you'll get relief! This happened to me w/ my first one.
Same I waddle like a granny sometimes with the pain x
Well I think it is a nerve from ur back the baby can be pressing on. You don't need to feel it also in ur back it can just hurt in butt or down ur leg. I say this Bcuz I've been dealing with major back issues for 13 yrs and I'm pregnant with number 5 but second pregnancy since my back injury. I'll get pain burning etc In My butt legs etc. Good luck. :) hope you feel better soon. I sympathize with you...know what pain is TO WELL.
