Neuropathic pain is a debilitating condition that affects millions of people worldwide. It is a type of chronic pain due to damage or malfunction of the nervous system. The type of pain can be burning, stabbing, or tingling and can be continuous or intermittent. To fully understand this condition, it’s important to examine its causes and diagnostic methods.
What is neuropathic pain?
It is a form of chronic pain that arises from dysfunction of the nervous system. This can occur due to physical nerve injuries, infections, systemic diseases, or neurological conditions such as diabetes. When nerves sustain damage or alterations, they can send pain signals to the brain even when there’s no actual source of pain. This phenomenon explains why people with neuropathic pain may perceive painful sensations without any apparent reason.
Causes
The causes of this condition can be different. Some triggering factors include:
- Physical injuries: Trauma or injuries that damage nerves can trigger neuropathic pain. This can occur following car accidents, falls, or surgical procedures.
- Systemic diseases: Conditions such as diabetes, shingles, HIV, and multiple sclerosis can damage nerves.
- Nerve compression: Nerve compression by tumors, herniated discs, or postural defects can lead to neuropathic pain.
- Toxic neuropathies: Prolonged use of medications or exposure to toxic substances can cause nerve damage.
Diagnosis
Diagnosing neuropathic pain can be challenging. In fact, there is no single definitive test to confirm its presence. Doctors often rely on symptoms, medical history, physical examinations, and sometimes specific diagnostic tests to identify it. Some of the diagnostic tools used include:
- Medical history: The doctor will gather detailed information about the patient’s medical history, including any traumatic events or previous illnesses.
- Physical examination: During the physical examination, the doctor will assess the patient’s reflexes, sensitivity, and muscle strength to identify signs of nerve damage.
- Electrophysiological tests: These tests, such as electromyography (EMG) and nerve conduction velocity, measure the electrical activity of nerves and can detect damage or abnormalities in nerve conduction.
- Imaging: In some cases, magnetic resonance imaging (MRI) or computed tomography (CT) scans may be useful to identify tumors or other causes of nerve compression.
- Blood tests: For some conditions, such as diabetes, blood tests may be used to confirm the diagnosis.
Once neuropathic pain has been diagnosed, treatment may vary from pain medications, physical therapies, behavioral therapies, and, in some cases, surgery to correct the underlying cause. Medications used to treat this condition often have significant side effects. Therefore, scientific research is increasingly driven to seek innovative solutions.
Supplements that Aid Neuropathic Pain
Algistat Complex is our supplement that promotes nervous system well-being. It’s a synergy between docosahexaenoic acid (DHA), from the omega-3 class, and clove essential oil, with high levels of eugenol and beta caryophyllene. Its components have demonstrated both in vivo and in vitro their antioxidant effects.
