A hot bath is already a great way to get some relief from muscle pain. But it gets better …

I discovered this while working on my own muscle knots, trying to tame an episode of low back pain, which is a never-ending job — they are always under control, more or less, but always threatening to come back, under the onslaught of chair work that I have saddled myself with by making a living as a writer.

This is what trigger points do, of course — they come back. It’s in their nature. And that’s why I’m always working on them, and always discovering new ways of doing it. It’s a creative challenge that never ends. It’s also why PainScience.com publishes a deliciously detailed tutorial about trigger points, which contains more detail about the bath trick, as well as hundreds of other basic and advanced tips and tricks.

The bath trick is a “together at last” trick: it came from combining two other classic tactics for releasing your own trigger points: the heat of a bath, with the pressure of a ball (see tennis ball massage). But the result is more than the sum of the parts, and it works better in some ways than anything else I’d come up with before. Suddenly I’m using the bath trick regularly myself, and recommending it to my readers.

Quick trigger points orientation

Muscle “knots,” usually known as myofascial trigger points (TrPs), are a factor in most of the world’s aches and pains. A trigger point is (hypothetically) a small patch of super-contracted and irritated muscle tissue, which can cause symptoms ranging from mild stiffness to extreme pain and a variety of odd side effects. They not only cause pain and problems directly, but also spring to life in response to almost all other painful problems, compounding and complicating them.

Even though the existence and importance of trigger points is well known to medical specialists and researchers, most doctors and therapists know little about them, so misdiagnosis and ineffective treatment are epidemic. For more information about how trigger points might be involved in your own medical history, see:

Absurdly simple instructions for trigger point release in the bath: simply …

  1. run a hot bath …
  2. climb in and get nice and warm and comfortable …
  3. and then bring in a ball! Trap the ball between your body and the bottom or the back of the tub, and cheerfully crush your trigger points with relieving pressure.

The Bath Trick

Run a hot bath & trap a ball between your body & the bottom or back of the tub to rub your back muscles — your buoyancy allows for excellent control with moderate pressures.

Many kinds of balls will work well, but a lacrosse ball or a KONG® brand rubber dog ball is perfect.

Play with the water level to increase or decrease your buoyancy and how firmly you are pressing down on the ball.

Pressure caution is still required! Although the buoyancy of the bath generally makes it relatively easy to regulate the pressure, compared to working on the ground with a ball, it can still be tricky, and I think the heat of the bath can also mask the intensity. I have bruised myself even when I thought I was being careful. Bruising is not cool and not therapeutic. Please be careful not to overdo it, especially at first!

Logos for Visa, Mastercard, and Amex.I accept Visa, Mastercard, and American Express. Discover and JCB are not supported for now, but I hope that will change in the not-too-distant future. Note that my small business does not handle your credit card info: it goes straight to the payment processor (Stripe). You can also pay with PayPal: for more information, click the PayPal button just below.

Paying in your own (non-USD) currency is always cheaper! My prices are set slightly lower than current exchange rates, but most cards charge extra for conversion.

Example: as a Canadian, if I pay $19.95 USD, my credit card converts it at a high rate and charges me $26.58 CAD. But if I select Canadian dollars here, I pay only $24.95 CAD.

Why so different? If you pay in United States dollars (USD), your credit card will convert the USD price to your card’s native currency, but the card companies often charge too much for conversion — it’s a way for them to make a little extra money, of course. So I offer my customers prices converted at slightly better than the current rate.

Buying “manually” with PayPal

The green buy buttons are for credit card orders only, which are processed instantly and automatically. But some customers prefer to use PayPal, instead of giving their card number to a small business. This small business never actually sees a credit card number, though: they go from your computer to your bank via Stripe.com [opens new tab], a big payment company with a solid reputation. Using a credit card here is as safe as using it in any store (probably safer, actually).

But you can still pay with PayPal, as long as you don’t mind being a bit more patient. PayPal orders are processed by me personally. To buy with PayPal, please “manually” login to PayPal and send payment of 19.95 USD to , add a note about which book you want, and … watch your spam folder.

Important reminders for PayPal orders!

  1. I process orders promptly during working hours, often within the hour; night orders are done early the next day.
  2. Specify the book you want! Just the topic is fine, e.g. “trigger points.”
  3. Watch your spam folder! Order confirmation emails are often mis-identified as junk email.
