I have temporomandibular joint syndrome, or TMJ. It known for the pain it causes in the face, head, neck, and upper body muscles. Sometimes my TMJ seems to become worse when I am under stress, and I am often under stress in social situations). I'm taking St. John's Wort again and have seen some improvement in regards to the anxiety. For the TMJ pain, I have been taking ibuprofen, as per campus nurse's recommendation; but I have stopped since the pain is not as bad as it used to be.
