**Severe Leg Pain After Massage: Causes and Relief** Massage treatments are intended to bring relaxation and relief, but in some cases, severe leg pain may occur. Possible causes include muscle overstretching due to excessive pressure or holding positions for too long and poor body mechanics from untrained therapists. If you experience severe leg pain after a massage, inform your therapist of discomfort during treatment and seek a second opinion if needed. Communicate boundaries and limitations to ensure tailored therapy.
