The deep tissue massage that you get, what is worked on exactly? And which area do you find gives you the most relief?
Many people have discs degradation/bulging, as is shown by MRIs turning up disc issues, yet the person had no symptoms prior or even post findings. So you may have a disc issue or it may be something else altogether, or a combination. There are certain assessment tests a physio will do to determine whether its disc causing neural/muscle issues or muscle imbalances or pelvic issues or lower extremity issues in ankles, knees, hips. So getting that full assessment is a good idea, especially considering it flares up quite often.
