Mum thumb is real, it has a name and you don't have to just live with it.
De Quervain's tenosynovitis is what happens when the tendons connecting your thumb to your wrist get repeatedly loaded without enough recovery time which is essentially the entire first year of having a baby. Lifting, feeding holds, carrying, gripping. Same tendons, same direction, all day long.
Most mums I work with have been managing it in silence for a while before they mention it, usually because nobody told them it was a thing they could actually do something about. Resting where possible, icing regularly, wearing a splint to take pressure off the tendon and seeing a physio if it's been going on for more than a few weeks, that's where to start.
At Reignite Women's Fitness, I make sure we're not adding to the problem. We modify, build supporting strength and don't push through pain just to get a session done.
