Heat
Heat can be soothing for muscle tension, stiffness, and chronic muscle tightness

Muscle pain can occur after exercise, unusual physical exertion, prolonged sitting, stress, or poor posture. It often feels like a pulling, pressing, stiff, or tender sensation. The back, neck, shoulders, legs, or arms are frequently affected.
Not all muscle pain is cause for concern. Muscle soreness after unfamiliar physical activity usually goes away on its own. However, recurring, severe, or unexplained muscle pain should be taken seriously.
Muscle pain can affect individual muscles, muscle groups, or larger areas of the body. It can occur suddenly or develop gradually.
Common symptoms include:
Muscle pain is often caused by overexertion, uneven strain, or a lack of exercise. Stress can also cause muscles to remain constantly tense.

Possible causes include:
Muscle soreness often occurs after unfamiliar or intense physical activity. The muscles feel tender, stiff, or painful. In most cases, muscle soreness does not occur immediately, but rather a few hours to a day after the activity.
Things that may help:
Severe pain, swelling, or significant limited mobility should be evaluated.
Tension often results from prolonged sitting, poor posture, stress, or repetitive strain. The neck, shoulders, back, and jaw area are particularly prone to this.
When muscles are tense, they remain tight for an extended period of time. As a result, they can become stiff, tender, and cause pain. Sometimes the discomfort radiates—for example, from the neck to the head or from the shoulder to the arm.
What can help:
Muscles need exercise, but they also need rest. Too little exercise can lead to muscle tension. Too much exercise or exercise that is too intense can cause overexertion and sore muscles.
A balanced approach is helpful:
Heat can be soothing for muscle tension, stiffness, and chronic muscle tightness
Cold can be more soothing for acute discomfort caused by overexertion, bruising, or swelling.
Muscles need energy, fluids, and nutrients. A balanced diet supports muscle metabolism, recovery, and performance.
