When you have muscular injuries, strains or trauma, “trigger points” develop. They can cause many kinds of pain including low back pain nyc nyc, tennis elbow, headaches, neck and jaw pain. They are also the cause of pain in the ankle, knee, hip, wrist, and shoulder joints but people sometimes mistake them for ligament injury, bursitis, tendinitis, or arthritis. Trigger points also cause other indirect symptoms such as dizziness, sinusitis, earaches, nausea, false heart pain, heartburn, genital pain, heart arrhythmia, and hands and feet numbness.
