How can i get my neck to stop being tight-feeling after the accident?

Physical therapy: Sudden movement of car accident cause muscle spasm in the neck, it takes few weeks to feel better -you need to see a doctor for muscle relaxant along with physical therapy

Muscle spasm: See fp for muscle relaxer (preferable one that doesn't make you sleep all the time). Moist heat to neck & shoulders will help relax muscles. Stretching exercises for neck & shoulders [see ilustration]. Shoulder shrugs will help relax trapezius. Therapeutic massage also beneficial & feels wonderful.
