Sore muscles are a common occurrence, often caused by exercise, strain, or injury. The medical term for muscle pain is myalgia, which can be classified as either localized (in one spot) or diffuse (all over the body). Localized muscle pain is typically related to events such as injuries or recent stress on a specific muscle group. On the other hand, diffuse muscle aches are usually associated with underlying conditions affecting the entire body, such as infections, diseases, or autoimmune disorders. While acute muscle soreness is felt immediately after intense exercise due to lactic acid buildup, delayed-onset muscle soreness (DOMS) sets in 12-48 hours after a workout due to microscopic tears in the muscles. Understanding the causes of muscle soreness is essential to determine the appropriate treatment, which may include rest, gentle stretching, massage, or professional medical care.

What You'll Learn

Intense exercise
To cause sore muscles through intense exercise, you can try the following:
- Eccentric exercises: These involve lengthening muscle contractions, such as walking or jogging downhill, or the lowering motion during a bicep curl or chest press. These types of movements can cause greater damage to your muscles and lead to more soreness.
- Increase volume or intensity: Upping the volume or intensity of your workout can cause muscle soreness. For example, if you usually lift 10-pound weights, try increasing the weight to 15 pounds.
- New exercises: Trying new exercises or workouts that are new to you can lead to muscle soreness. This is because your muscles are not yet accustomed to the new movements or demands placed on them.
- Inadequate rest: Not giving your muscles adequate time to rest and recover can lead to more intense soreness. It is important to build in rest days and focus on active recovery to allow your muscles to heal.
While causing sore muscles through intense exercise can be intentional, it is important to note that excessive soreness or pain can be a sign of overexertion or injury. It is always important to listen to your body and seek medical attention if necessary.

Lack of movement
Muscle soreness and stiffness can be caused by a lack of movement. This is especially common in desk jobs involving long hours of sitting, which can cause muscle stiffness and pain.
Periods of inactivity can lead to acute muscle stiffness, which is a feeling of pain or tightness in your muscles. This can be caused by dehydration and electrolyte imbalances, which increase your chances of muscle stiffness and soreness. Therefore, it is recommended to drink at least 64 ounces of water daily, and possibly more depending on your activity levels and body size.
Simple treatments can usually relieve discomfort and loosen tight muscles. Stretching, exercising more frequently, and improving your posture can all help relieve muscle stiffness. However, it is important to note that muscle stiffness can sometimes point to an underlying, more serious infection or medical condition. If muscle stiffness occurs alongside symptoms such as headaches, fever, fatigue, sore throat, or chest pain, it is recommended to see a healthcare provider.

Stress
Additionally, stress can affect your digestive system, causing pain, gas, diarrhoea, constipation, irritable bowel syndrome, and acid reflux. When you are stressed, your muscles tense up, and when the stress subsides, they release that tension. This can result in muscle soreness and pain, similar to the feeling after strenuous exercise. Emotional stress and physical stress from work or maintaining prolonged positions without movement can also contribute to muscle soreness.
Furthermore, stress and anxiety can lead to clenching and muscle tension. During periods of anxiety, your brain triggers a fight-or-flight response, tensing your muscles as if preparing for rapid action. This can cause a buildup of lactic acid in the muscles, resulting in soreness. Inactivity and decreased physical activity due to stress can weaken muscles and deprive them of adequate blood flow, oxygen, and nutrients, further contributing to muscle pain.
Poor posture and postural adjustments due to stress or anxiety can also put strain on muscle groups, leading to localized muscle soreness. Sleep deprivation caused by stress can increase muscle aches because the body doesn't get the restorative benefits of a good night's rest. To alleviate stress-related muscle soreness, it is important to address the underlying stress or anxiety and practice healthy coping mechanisms such as physical activity, creativity, and self-care.

Dehydration
When the body is dehydrated, blood flow to the muscles is reduced due to decreased blood pressure and perfusion pressure. This reduction in blood flow can lead to structural, contractile, and enzymatic protein denaturation, as well as myofiber and connective damage. As a result, dehydrated individuals may experience delayed-onset muscle soreness (DOMS), which is characterised by muscular pain, dull, diffuse pain, tenderness, stiffness, swelling, and decreased strength in the affected muscles. These symptoms typically last from one to four days after the exercise.
The risk of developing DOMS can be lowered by ensuring adequate hydration before, during, and after exercise. Water is essential for maintaining proper body function and preventing dehydration. It is recommended to drink six to eight eight-ounce glasses of water per day, or some suggest drinking half of your body weight in ounces. However, individual water needs may vary, and it is always important to listen to your body and adjust your fluid intake accordingly.
In addition to water, individuals can also consume sports drinks or oral rehydration solutions, which contain electrolytes to help replenish those lost through sweating. It is important to note that dehydration can also be caused by not consuming enough water in general, not just during exercise. Therefore, it is crucial to stay hydrated throughout the day, every day.
Furthermore, dehydration can also lead to a lack of lubrication in the joints, causing achy and painful joints. This can be prevented by ensuring adequate fluid intake, as mentioned earlier.

Massage
Deep tissue massages involve significant manipulation and pressure on the muscles, which can cause the release of toxins that have accumulated within muscle fibres and knots. These toxins refer to metabolic waste products, such as lactic acid, that build up in muscles due to physical activity and stress. The pressure exerted during the massage helps break down these waste products, releasing them into the bloodstream. This release of toxins can cause temporary muscle soreness as the body works to flush them out and initiate the healing process.
The soreness experienced after a deep tissue massage typically lasts between 24 to 48 hours and is considered a normal part of the body's response to the treatment. However, it is important to note that soreness after a massage should not feel like intense or sharp pain. If you experience nerve pain, characterised by sharp and stabbing sensations, it is crucial to consult a healthcare professional.
To prevent and manage muscle soreness after a massage, here are some key considerations:
- Communication: During the massage, communicate any discomfort or pain to your therapist so they can adjust their techniques. Open communication ensures the massage remains therapeutic and reduces the likelihood of undue discomfort.
- Hydration: Proper hydration is essential before and after a massage. Staying hydrated helps the body flush out toxins released during the massage and supports the recovery process.
- Stretching: Gentle stretching routines after a massage can help ease muscle tension and soreness. Focus on stretching the areas that feel particularly sore or tense, improving flexibility and promoting blood circulation.
- Heat and Cold Therapy: Applying heat or cold therapy can provide soothing relief to sore muscles. A warm bath or hot shower can help relax muscles and alleviate discomfort. Alternatively, using ice packs or taking an ice bath can reduce inflammation and provide a numbing effect to manage pain.
- Rest: Allow your body time to rest and recover after a massage. Avoid challenging physical activities that may further stress your muscles. Resting helps your muscles relax and enables your body to fully benefit from the massage therapy.
- Pain Relief: In some cases, non-prescription pain relievers, such as ibuprofen or acetaminophen, can be used cautiously and under the guidance of a healthcare provider. These medications can help manage discomfort but should be used as directed.
- Experimentation: Experiment with different types of massages, pressures, and therapists to find what suits your goals and needs. Consistent massages can help your body adapt to the treatment, reducing post-massage soreness over time.
By following these considerations, you can effectively induce and manage muscle soreness associated with massage therapy.
