So I'm 13 days postpartum and my recovery started out really good but as of late I'm getting terrible lower back pain along with pain in my sides which I think is gas. It subsides if I take a Percocet but it comes back as soon as the pill wears off. Heated prune juice has helped on the gas. Has anyone tried Icy Hot or any of those types of things for back pain? I believe this pain may be associated with the epidural.
