Magnetic back support belts are great for back pain but can also help avoid back pain by wearing them when you travel.
I have recently come back from a holiday which involved two long hall flights and I used a magnetic belt as well as a heat patch for both journeys. I am firm believer that if you go armed with a few different types of pain relief you can manage a journey pain free.
I would never travel without my coccyx cushion and have worn heat pads for a long time now but previously I wore a support back girdle which was made for me after one of my spinal surgeries, but it was far from comfortable to wear.
The Bad Back Company have a vast array of products for pain and their Back Support Belt has 20 High Grade ceramic magnets that generate a constant magnetic field over your low back. It costs £39.99 and you will never need to re charge the magnets. Their belt has a high quality adjustable support in a double layer for varied degrees of support and compression for your back. There are also a number of other Back Support Belts without the magnets also available from The Bad Back Company.
Heat has always helped me and it has 3 flexible boned supports to support your lumber spine and keep your muscles and joints warm to reduce muscular spasm or discomfort.
Please check their caution note for people who have pacemakers, defibrillators, insulin pumps or similar devices that are powered by a battery whether as an implant or an external unit. It is also not recommended for use during pregnancy. You can also watch a video about the back support on The Bad Back Company page.
The heat pads I use the Thermacare Advanced Back Pain relief pads which last up to 16 hours and are available from Amazon at £5.50 for 2.
