Postnatal back pain is very common. The body spends nine months redistributing load around a shifting centre of gravity, then immediately takes on hours of carrying, feeding, and sleeping in whatever position gets the baby down. The back that was holding everything together is now doing that on no sleep.
The difficulty is that many standard pain management options are not appropriate while breastfeeding, and most require time that does not exist. Physio appointments need someone to watch the baby. Heat patches give temporary relief. Painkillers feel like the wrong answer.
TENS is drug-free. It works through the skin, not the bloodstream. There is no systemic absorption, no compounds passed through breastmilk. It takes under three minutes to apply, and a session lasts 20 minutes — a feed window, a nap window.
It is not a cure for postnatal back pain. But it is a consistent, repeatable way to reduce it to a manageable level, without adding another complication to an already full picture.
