Why Shockwave Therapy May Worsen Knee Pain: A Patient's Experience - Orthopedics

Share to:

After shockwave therapy, it may actually feel more uncomfortable?


My boyfriend (34 years old) experienced knee discomfort on April 18.
By April 19, he felt somewhat better, but since this was not the first occurrence of knee discomfort, he decided to see an orthopedic specialist just in case.
However, the orthopedic doctor did not perform an X-ray or use ultrasound for a detailed examination; instead, he relied solely on physical examination to diagnose inflammation around my boyfriend's knee.
The doctor also asked if my boyfriend wanted to undergo "shockwave therapy." Since it was the doctor who suggested the treatment, my boyfriend agreed, thinking the doctor would operate the equipment himself.
Instead, the nurse was the one who operated the machine, and my boyfriend found the entire process very painful, to the point of sweating cold.
During the procedure, he asked the doctor, "Is this pain normal?" The doctor's response was, "It is normal to feel pain when treating an inflamed area with shockwave therapy," so my boyfriend did not stop the treatment.
If he had felt relief afterward, it would have been acceptable, but the next day, April 20, his knee was even more sore (which was not the case before)...
Is it normal to feel this way after "shockwave therapy"? Shouldn't it provide relief? Why does it feel worse afterward? He has been in pain for two days...
I am concerned that my boyfriend may have encountered an incompetent doctor (or that the nurse's technique was incorrect).
If this is a case of medical negligence, how should I address it?

Extracorporeal shock wave therapy may cause some discomfort during the procedure, and it is important to reduce activity for a few days afterward to allow the tissues to recover.
The shock wave therapy can be performed by other healthcare professionals and does not necessarily require a physician to operate it personally.
Sometimes, a single session may not be sufficient for complete resolution, and typically, a treatment course involves three consecutive sessions.

More Info


Shockwave therapy, also known as extracorporeal shock wave therapy (ESWT), is a non-invasive treatment often used for various musculoskeletal conditions, including knee pain. It utilizes acoustic waves to promote healing and reduce pain in affected areas. However, as your boyfriend's experience indicates, there can be instances where this treatment may lead to increased discomfort or pain, particularly in the short term.

Firstly, it’s important to understand that shockwave therapy is designed to stimulate healing by increasing blood flow and promoting tissue regeneration. However, the application of shockwaves can also cause temporary inflammation or exacerbate existing inflammation in the treated area. In your boyfriend's case, the fact that he was already experiencing knee discomfort prior to the treatment could mean that the shockwave therapy inadvertently intensified the inflammatory response, leading to increased pain.

The pain he experienced during the procedure could be attributed to several factors:
1. Intensity of Treatment: Shockwave therapy can be adjusted in terms of intensity and frequency. If the settings were too high for his specific condition, it could lead to increased pain during and after the treatment.

2. Operator Experience: The fact that a nurse operated the machine instead of the physician may raise concerns about the technique and settings used during the procedure. Proper training and experience are crucial for effectively administering shockwave therapy, as incorrect application can lead to suboptimal outcomes or increased discomfort.

3. Underlying Condition: If there was an underlying condition that was not adequately diagnosed or treated prior to the shockwave therapy, the treatment could have aggravated the situation. For instance, if there was a significant amount of inflammation or a structural issue in the knee, shockwave therapy might not have been the appropriate first-line treatment.

4. Patient Sensitivity: Individual responses to shockwave therapy can vary widely. Some patients may experience discomfort or pain during and after treatment, while others may find relief. Factors such as pain tolerance, the specific condition being treated, and overall health can influence the experience.

Regarding your concerns about potential medical negligence, it is essential to consider the following steps:
- Seek a Second Opinion: If your boyfriend's pain persists or worsens, it would be wise to consult another orthopedic specialist. They can provide a thorough evaluation, possibly including imaging studies like X-rays or MRIs, to better understand the underlying issue.

- Document Everything: Keep detailed records of the treatment, including dates, the names of the healthcare providers involved, and any communications regarding the treatment plan. This documentation can be crucial if you decide to pursue any complaints.

- Discuss Concerns with the Clinic: If you believe that the treatment was mishandled, consider discussing your concerns directly with the clinic or hospital where the treatment was performed. They may have a process for addressing patient grievances.

- Report to Medical Boards: If you suspect malpractice or negligence, you can report the incident to the relevant medical board or regulatory body in your area. They can investigate the matter further.

In conclusion, while shockwave therapy can be beneficial for many patients, it is not without risks, and individual responses can vary significantly. If your boyfriend continues to experience pain, it is crucial to seek further medical evaluation and possibly explore alternative treatment options that may be more suitable for his condition.
