What Are the Negative Side Effects of Shockwave Therapy?
Radial shockwave therapy has become a widely used treatment for musculoskeletal pain, sports injuries, and chronic soft tissue conditions. It is commonly offered by physiotherapists, chiropractors, and sports medicine professionals as a non-invasive alternative to surgery or injections.
While the treatment is generally considered safe, patients often ask about potential side effects before starting therapy. Understanding these effects helps set realistic expectations and supports better recovery outcomes.
This guide explains the possible negative side effects of shockwave therapy, why they occur, how long they last, and when medical advice should be sought.
What Is Radial Shockwave Therapy?
Radial shockwave therapy (RSWT) is a non-surgical treatment that uses acoustic pressure waves to stimulate healing in injured or inflamed tissues.
A handheld device delivers controlled pulses into the affected area, triggering biological responses such as improved circulation, tissue regeneration, and pain reduction.
Common Uses
- Chronic lower back pain
- Tendon disorders (e.g. Achilles tendinopathy, tennis elbow)
- Plantar fasciitis
- Muscle tightness and trigger points
- Shoulder pain
- Sports-related injuries
Because it promotes the body’s natural healing processes, it is often used when conventional treatments have not delivered sufficient results.
Are Side Effects Common?
For most patients, shockwave therapy is well tolerated. Side effects, when they occur, are typically mild and short-lived.
Unlike invasive procedures, this therapy:
- Does not involve incisions
- Does not require anaesthesia
- Does not introduce medication into the body
However, as it stimulates tissue repair and increases blood flow, temporary reactions can occur as part of the healing response.
Common Side Effects of Shockwave Therapy
1. Mild Pain or Tenderness
Temporary discomfort in the treated area is the most frequently reported side effect. This occurs because the therapy stimulates already sensitive or injured tissues.
Patients may notice:
- Localised soreness
- Mild aching
- Sensitivity to touch
This usually settles within 24 to 48 hours.
2. Skin Redness
Redness or warmth at the treatment site can occur due to increased blood circulation. This is a normal physiological response and often indicates improved blood flow to the area.
It typically fades within a few hours.
3. Mild Swelling
Slight swelling may develop as the body initiates an inflammatory healing response. This is part of the natural repair process rather than a harmful reaction.
Swelling is usually minimal and resolves quickly.
4. Bruising
Small superficial bruises can occasionally appear, particularly in patients with sensitive skin or fragile capillaries.
This is harmless and generally disappears within a few days.
5. Tingling or Numbness
Some patients report temporary tingling or mild numbness following treatment. This is linked to nerve stimulation during the procedure.
The sensation is short-lived and typically resolves within hours.
Less Common Side Effects
Temporary Increase in Pain
A small number of patients may experience a brief increase in pain after the initial session. This is often due to the activation of the body’s healing response and the breakdown of damaged tissue.
Symptoms usually improve after subsequent sessions.
Skin Sensitivity or Irritation
In rare cases, the skin may feel slightly irritated due to repeated pressure from the device.
Possible symptoms include:
- Mild itching
- Temporary sensitivity
- Local discomfort
These effects resolve without medical intervention.
Why Do Side Effects Occur?
The side effects of radial shockwave therapy are closely linked to its mechanism of action.
The treatment stimulates:
- Increased blood circulation
- Cellular regeneration
- Collagen production
- Breakdown of scar tissue
- Controlled inflammatory response
As the body begins repairing damaged tissue, mild symptoms such as soreness or swelling may occur. In most cases, these are signs that the therapy is working effectively.
How Long Do Side Effects Last?
Side effects are usually short-term and resolve without treatment.
Typical Recovery Timeline
- Redness: a few hours
- Soreness: 24 to 48 hours
- Swelling: 1 to 2 days
- Bruising: several days
Most patients can continue normal daily activities immediately after treatment.
How to Minimise Side Effects
Following simple aftercare advice can help reduce discomfort and improve results.
Post-Treatment Recommendations
- Avoid strenuous activity for 24 hours
- Stay well hydrated
- Follow prescribed stretching or rehabilitation exercises
- Maintain good posture
- Apply a cold compress if swelling occurs
Adhering to professional guidance enhances recovery and treatment effectiveness.
Who Should Avoid Shockwave Therapy?
Although safe for most individuals, shockwave therapy may not be suitable for:
- Pregnant women
- Individuals with blood clotting disorders
- Patients with local infections
- Those with certain neurological conditions
- Individuals with tumours near the treatment area
- Patients on strong anticoagulant medication
A thorough clinical assessment is essential before starting treatment.
Benefits vs Risks
Key Benefits
- Non-invasive treatment
- Minimal downtime
- Drug-free pain relief
- Promotes natural healing
- Effective for chronic conditions
Potential Risks
- Temporary soreness
- Mild swelling
- Skin redness
- Occasional bruising
Overall, the benefits significantly outweigh the risks, particularly when treatment is delivered by a qualified professional.
Why Healthcare Professionals Recommend It
Shockwave therapy is widely recommended because it targets the underlying cause of pain rather than simply masking symptoms.
By enhancing tissue repair and improving circulation, it supports long-term recovery and reduces the likelihood of recurrence.
Radial Shockwave Therapy at Proback
At Proback, treatment plans are designed to address both symptoms and root causes of musculoskeletal pain.
Shockwave therapy is often integrated with:
- Chiropractic care
- Spinal decompression
- Postural correction
- Rehabilitation programmes
- Advanced pain management techniques
This combined approach improves recovery outcomes and helps prevent future injuries.
When Should You Seek Advice?
You should consult a healthcare professional if:
- Pain persists beyond 48 hours after treatment
- Symptoms worsen instead of improving
- You experience unusual swelling or discomfort
- The treated area becomes increasingly sensitive
Early guidance ensures safe and effective treatment progression.
Final Verdict
Radial shockwave therapy is a safe and effective treatment for many musculoskeletal conditions. While mild side effects such as soreness, redness, or swelling can occur, they are usually temporary and part of the body’s natural healing response.
For individuals seeking a non-invasive solution to chronic pain, it remains a reliable and clinically supported option.
If you are considering treatment, a professional assessment will help determine whether shockwave therapy is appropriate for your condition and recovery goals.
