Laser for chronic pain is an effective method of pain relief offered at a Merrylands physical therapy clinic.
Chronic pain is a debilitating condition that affects millions of people worldwide. Whether it’s due to arthritis, nerve damage, or lingering injuries, chronic pain can significantly impact daily life, making even simple activities difficult. While traditional treatments such as medication and physiotherapy offer relief, they often come with limitations and side effects.
Laser therapy has emerged as a promising alternative for managing chronic pain. This non-invasive and drug-free treatment uses light energy to stimulate healing, reduce inflammation, and alleviate pain.
What is Chronic Pain?
Chronic pain is persistent pain that lasts for more than three months, often continuing even after the underlying cause has healed. It can stem from various medical conditions, injuries, or nerve damage, affecting different parts of the body.
Common Causes of Chronic Pain
- Arthritis: Inflammation of the joints leading to stiffness and discomfort.
- Fibromyalgia: A disorder characterised by widespread musculoskeletal pain.
- Neuropathy: Nerve damage causing tingling, burning, or shooting pain.
- Back Pain: Commonly caused by herniated discs, spinal conditions, or muscle strain.
- Migraines: Severe headaches often accompanied by nausea and sensitivity to light.
Chronic pain can lead to sleep disturbances, anxiety, depression, and reduced mobility. It affects work productivity, social interactions, and overall well-being, making effective treatment crucial.
What is Laser Therapy?
Laser therapy, also known as photobiomodulation therapy (PBMT), is a medical treatment that uses specific wavelengths of light to penetrate tissues and promote healing. Unlike surgical lasers, which cut through tissues, therapeutic lasers work on a cellular level to relieve pain and inflammation.
How Does Laser Therapy Work?
The process involves directing low-level or high-intensity laser beams at the affected area. The light energy is absorbed by cells, triggering a series of biological reactions that:
- Stimulate tissue repair and regeneration
- Increase blood circulation
- Reduce swelling and inflammation
- Block pain signals from reaching the brain
Types of Laser Therapy for Chronic Pain
1. Low-Level Laser Therapy (LLLT)
Uses low-intensity light to stimulate cell function.
Commonly used for arthritis, neck pain, and soft tissue injuries.
Safe with minimal side effects.
2. High-Intensity Laser Therapy (HILT)
Delivers stronger laser energy for deep tissue penetration.
Effective for severe joint pain, back pain, and nerve pain.
May cause mild warmth or tingling during treatment.
3. Cold Laser Therapy
Non-thermal laser treatment that promotes healing without heat.
Ideal for muscle recovery, tendon injuries, and inflammation reduction.
Used in both clinical settings and home-use devices.
How Laser Therapy Works for Chronic Pain
Laser therapy works by stimulating the body’s natural healing processes. Here’s how:
1. Cellular Repair and Regeneration
The laser light penetrates deep into the tissues, reaching the mitochondria (the energy powerhouse of cells). This boosts ATP (adenosine triphosphate) production, which fuels cellular repair and growth.
2. Reduced Inflammation and Swelling
Inflammation is a key factor in chronic pain. Laser therapy reduces the production of pro-inflammatory chemicals while increasing anti-inflammatory responses, leading to pain relief and tissue recovery.
3. Nerve Function Restoration
Chronic pain often results from nerve damage. Laser therapy improves nerve conductivity and reduces nerve sensitivity, helping to restore normal function.
4. Enhanced Blood Circulation
By increasing blood flow to the affected area, laser therapy delivers oxygen and nutrients necessary for healing while removing toxins and waste products.
Benefits of Laser Therapy for Chronic Pain
Laser therapy has gained popularity due to its effectiveness in managing chronic pain without the need for drugs or surgery. Below are some of its key benefits:
1. Non-Invasive and Drug-Free Treatment
Unlike medications that come with potential side effects and risks of dependency, laser therapy is completely drug-free. It does not require injections, incisions, or any surgical intervention, making it a safer alternative for long-term pain management.
2. Long-Lasting Pain Relief
Many patients report significant pain reduction after a few sessions. The therapy not only alleviates symptoms but also promotes healing at a cellular level, offering long-term benefits rather than just temporary relief.
3. Reduces Inflammation and Swelling
Inflammation is a major contributor to chronic pain. Laser therapy helps to decrease inflammation by improving blood circulation and stimulating anti-inflammatory responses in the body.
4. Enhances Mobility and Functionality
Chronic pain can limit movement and flexibility. By reducing pain and inflammation, laser therapy helps patients regain mobility, allowing them to perform daily activities with greater ease.
5. No Downtime or Recovery Period
Unlike surgical procedures, which often require long recovery times, laser therapy allows patients to resume their normal activities immediately after a session. This makes it an ideal choice for those with busy schedules.
Common Conditions Treated with Laser Therapy
Laser therapy has been successfully used to treat various chronic pain conditions, including:
1. Arthritis and Joint Pain
Arthritis, including osteoarthritis and rheumatoid arthritis, can cause severe joint pain and stiffness. Laser therapy helps by reducing inflammation and promoting cartilage repair.
2. Back Pain and Sciatica
Chronic back pain, often caused by herniated discs or muscle tension, responds well to laser therapy. It can also help with sciatica, a condition where pain radiates from the lower back down to the legs.
3. Fibromyalgia
Fibromyalgia is a condition characterised by widespread muscle pain and fatigue. Laser therapy can help reduce muscle tenderness and improve energy levels.
4. Neuropathy
Nerve-related pain conditions, such as diabetic neuropathy, can be challenging to manage. Laser therapy enhances nerve function and helps reduce burning or tingling sensations.
What to Expect During a Laser Therapy Session
1. Procedure and Duration
A laser therapy session typically lasts between 10 to 30 minutes, depending on the treatment area. The patient sits or lies comfortably while the practitioner directs the laser beam to the affected area.
2. Sensations During Treatment
Most patients report feeling a mild warming or tingling sensation during the procedure. The treatment is generally pain-free, and no anaesthesia is required.
3. Post-Treatment Care
There is no special aftercare needed, but it is advisable to stay hydrated and avoid strenuous activities immediately after the session. Some people may experience mild soreness, similar to a post-workout feeling, which resolves quickly.
Risks and Side Effects of Laser Therapy
1. Potential Concerns
Laser therapy is generally safe, but some mild side effects may include:
- Temporary redness or warmth in the treated area
- Mild swelling or soreness
- Sensitivity in the skin after treatment
2. Who Should Avoid Laser Therapy?
While laser therapy is safe for most people, it is not recommended for:
- Pregnant women (especially over the abdomen)
- Patients with cancerous tumours in the treatment area
- Individuals with photosensitivity disorders
FAQs
1. Is laser therapy safe for everyone?
Laser therapy is safe for most people, but it should be avoided by pregnant women and individuals with cancerous tumours in the treatment area.
2. How many sessions are needed for chronic pain relief?
Most patients need 6-12 sessions for noticeable improvement, though some feel relief after just 3-5 sessions.
3. Can laser therapy completely cure chronic pain?
Laser therapy does not guarantee a cure but helps manage pain and promotes healing, leading to long-term relief.
4. Does laser therapy have any side effects?
Side effects are rare but may include temporary redness, warmth, or mild swelling in the treated area.
