Sciatica can be brought on by compression of the nerve by surrounding tissues. When that compression is found in the hip area, a group of muscles, that originate at the tailbone and attach to the hip, are often the culprit. This is often referred to as Piriformis Syndrome. The piriformis is the largest of those muscles. Along with pain, symptoms such as numbness and tingling and weakness can also be present.
The good news is that this issue can be treated conservatively with a very high success rate. When issues are found in this region, a hands-on approach can be used to break up adhesions and scar tissue, as well as reduce any muscle spasms that are contributing to the problem. This will help to take the pressure off of the nerve, allowing the symptoms to ease and eventually resolve.
