I can't agree with Dr. Rebecca Sanders enough on getting curious about the emotional component of your physical tension. My modality is EFT Tapping, so I'll be looking at your question through that lens. Tapping utilizes different endpoints (acupressure points) along the meridian lines of the body. When there is a block of some sort, the energy in our body can't flow freely (think of a garden hose with a kink in it). Energetic blocks can form for a variety of reasons, but they're likely caused by emotion(s) that our body hasn't processed, which can show up as a physical manifestation.
The great thing about Tapping is you can focus on the physical sensation directly and get relief. However, unless the emotional root is also treated, the results might not be permanent.
