    Iliocostalis Thoracis Trigger Point Treatment

    If you are interested in treating back pain caused by trigger points, The Trigger Point Therapy Workbook explains the trigger point phenomenon and muscle pain in everyday language. Diagrams and step-by-step instructions help you locate which muscles are contributing to your pain, how to find the trigger point and treat it. Treating trigger points has helped many people resolve their back pain issues. This book is a must-have for anyone interested in finding the cause and treating muscle pain.

    If you are not comfortable initiating self-treatment, find a massage therapist, physical therapist, or chiropractor knowledgeable about trigger point therapy. They can teach you about specific trigger points related to your pain.

    Trigger points respond best to several short treatments throughout the day.

    If you use the workbook, you will need a tool to treat the back muscles. One tool that is recommended is a massage ball. You place the ball between your back muscles and a wall. Using your body, you roll the ball up and down to massage the muscle.

    Another tool is the Thera Cane Massager. The massage tool can be used standing or sitting. It allows you to reach and treat hard-to-reach areas of the body easily. The Thera Cane is easy to use for anyone who has balance or mobility problems.

    TWD Recommends

    Cureve Hot Cold Pack can be used for warm and cold treatments. It is recommended that cold packs be applied for 20-minutes after a TrP treatment. Use a warm treatment when the muscle is tight and needs to relax.

    To prolong the effects of the cold pack, use Biofreeze Cooling Gel. Biofreeze works like ice in that it cools the area and may help reduce inflammation. Rub the gel into the back 15-20 minutes after removing the ice pack. It can be applied up to 3 times a day for pain relief. Biofreeze is used and recommended by therapists and doctors for musculoskeletal injuries and pain.
