What should you know about natural muscle relaxer?

Muscles can tighten after overuse, an awkward position, stress, dehydration or an injury. Gentle movement, warmth and slow breathing may reduce guarding for some people. A muscle relaxer supplement or herbal product is not automatically harmless: products can interact with medicines, affect alertness or be unsuitable with pregnancy, kidney disease or other conditions.

A [Back Muscle Spasm](/symptoms/back-muscle-spasm/) is a sudden tightening in the back; [Muscle Cramps](/symptoms/muscle-cramps/) are involuntary contractions that can affect other areas. Their triggers and treatment may differ.

Stop the activity that triggered the tightness, then try comfortable range-of-motion movements rather than forceful stretching. A warm shower or heat pack may feel soothing; protect your skin from excessive heat. Drink fluids normally and review exercise load, sleep and prolonged sitting. Do not combine supplements with prescribed muscle medicines without checking with a pharmacist or clinician.

Seek medical advice when cramps recur, spasms last, pain follows an injury, or tightness keeps you from sleeping or walking. Get urgent help for new weakness, spreading numbness, severe swelling, fever, chest symptoms or a loss of bladder or bowel control.

What may be triggering my muscle tightness? Is heat, stretching or physiotherapy suitable for me? Could any medicine or supplement be contributing? Which symptoms would mean I should stop self-care and seek help?
