I was told celebrex and flexeril was a no no by my ob and by the pediatrician. I was on it for several years and stopped it when I got pregnant and was told I could not resume taking it until after baby was weaned. Im not sure about the other meds. Sorry I can't be of more help.
My Obe and my pediatrician both told me celebrex is fine for breastfeeding.
The pediatrician also told me I could also try tumeric capsules to assist with reducing inflammation. It turned my milk yellow, but is safe for the baby.
I have been having issues with reactive arthritis since the birth of my baby, though it does seem to be slowly settling down.
I hope your back can settle down a bit.
I'm taking Percocet . My dr said that, although it's true that whatever you take passes into your breast milk, so little of it is transferred that it has no effect on baby. :)
I'm on Percocet right now bc during delivery I tore really bad... My ob wrote it for me and says its ok
