It depends. Let’s say you come to see me when you’re not really uncomfortable. But when I work on your muscles, I can feel that they’re congested, and you can feel that they’re sore.
That’s the best case. The muscles need massage because of the extra challenges being placed on them, but they haven’t caused you pain or discomfort yet. We got to them before they got symptomatic. Let’s call this Stage I.
Stage II is when most of my pregnant clients come in for a massage. Something is hurting. Your back muscles are at least uncomfortable, maybe painful. Let’s call this Stage II.
For Stages I and II, an hour is usually enough. Because your body is changing shape daily and new demands are being placed on your muscles every day, you may want another massage in a few weeks. Regularly scheduled hour-long massages can be perfect.
If in addition to back pain you have other issues, like a sciatica-type pain, or your ankles are swelling, then an hour and a quarter is better. Let’s call this Stage III.
With swelling, it takes time to move lymphatic fluid; you have to go slow, at the speed of the lymphatic system. Even if your hands, feet, and ankles aren’t actually swollen, but are starting to feel puffy, it may make sense to go for the hour and a quarter.
