Risks of Overheating During Shortwave Therapy: What You Need to Know

What happens if shortwave therapy is too hot?

Recently, I have been experiencing inflammation of the ligaments near my coccyx.
My doctor prescribed six sessions of shortwave diathermy and electrical therapy.
During my rehabilitation session yesterday, the therapist performed shortwave treatment and reminded me to report if it felt too hot.
It felt significantly warmer than during previous sessions, almost like the temperature of a hot shower.
At the time, I wasn't sure if that was normal, so I didn't say anything.
However, I later found out that shortwave therapy should only feel warm or not at all.
After returning home, I noticed that the pain points were more painful when I woke up the next day.
I'm wondering if this could potentially cause burns, as mentioned online.
Is there any risk involved? If I continue to feel uncomfortable, can I see a family medicine doctor? The rehabilitation department is closed tomorrow, so I can't make an appointment.
Thank you.

Excessive intensity of shortwave therapy may cause burns, leading to damage to the skin or deeper tissues.
If discomfort occurs during treatment, it is important to immediately inform the therapist.
Family medicine can address general issues, but for concerns related to rehabilitation, it is advisable to consult a rehabilitation specialist for evaluation and treatment.
In case of emergencies, such as severe pain or noticeable redness and burns, prompt medical attention should be sought.
Any relevant specialty can be consulted, including rehabilitation medicine, orthopedics, surgery, or family medicine.
If symptoms are mild, resting and avoiding further irritation of the affected area is recommended until a rehabilitation physician can assess and determine further management.

More Info

Shortwave therapy, also known as diathermy, is a form of physical therapy that uses electromagnetic waves to generate heat within body tissues. It is commonly used to relieve pain, reduce inflammation, and promote healing in various musculoskeletal conditions, including ligament injuries. However, as with any therapeutic modality, there are risks associated with its use, particularly concerning overheating.

Risks of Overheating During Shortwave Therapy
1. Burns: One of the most significant risks of overheating during shortwave therapy is the potential for burns. If the device is applied for too long or at too high a temperature, it can cause thermal burns to the skin and underlying tissues. This is particularly concerning in areas with less fat or muscle, where the skin is closer to the bone.

2. Tissue Damage: Excessive heat can lead to damage not only to the skin but also to deeper tissues. This can result in inflammation, increased pain, and delayed healing. In some cases, it may exacerbate the condition being treated rather than alleviate it.

3. Dehydration of Tissues: Overheating can lead to dehydration of the tissues, which can impair their function and healing capacity. This is particularly relevant for connective tissues like ligaments, which require adequate hydration for optimal performance and recovery.

4. Increased Pain: As you experienced, overheating can lead to increased pain in the treated area. This can be due to inflammation or irritation of the nerves in the area, which may be exacerbated by the heat.

5. Circulatory Issues: Shortwave therapy increases blood flow to the area being treated. While this is generally beneficial, excessive heat can lead to vascular complications, especially in individuals with pre-existing circulatory issues.

Recommendations for Safe Use
- Temperature Monitoring: It is crucial to monitor the temperature during treatment. If you feel that the heat is excessive or uncomfortable, you should communicate this to your therapist immediately. The treatment should feel warm but not hot enough to cause discomfort.

- Duration of Treatment: Ensure that the duration of the treatment is appropriate. Shortwave therapy sessions typically last between 10 to 20 minutes, depending on the condition being treated. Prolonged exposure can increase the risk of overheating.

- Follow-Up: If you experience increased pain or discomfort after treatment, it is essential to follow up with your healthcare provider. They can assess whether the treatment plan needs to be adjusted or if alternative therapies should be considered.

- Consultation with a Physician: If the discomfort persists, it is advisable to consult with your primary care physician or a specialist. They can evaluate your symptoms and determine if further intervention is necessary.

Conclusion
In summary, while shortwave therapy can be an effective treatment for conditions like ligament inflammation, it is essential to be aware of the risks associated with overheating. If you experience excessive heat during treatment, it is crucial to communicate this to your therapist. Additionally, if you notice increased pain or discomfort following treatment, do not hesitate to seek medical advice. Your health and safety should always be the priority in any therapeutic setting.
