What causes neuropathy?
Peripheral Neuropathy is a condition in which peripheral nerves, most commonly the hands, feet, or face, become inflamed due to various causes, and can cause pain or numbness as a side effect.
- Diabetes with poor blood sugar control
- Some types of neuropathy that occur spontaneously or after certain infections, such as shingles (postherpetic neuralgia)
- Diseases that cause nerve compression, such as cervical spine, waist, back nerve compression, or tendonitis compressing a nerve in the wrist area.
- Muscle and tendon inflammation
- It may occur after traumatic injury to the nervous system or after surgery.
- It may also occur in association with other chronic diseases affecting the nervous system, such as stroke or cancer.
- Vitamin B deficiency 1 (Vitamin B1), Vitamin B6 (Vitamin B) and Vitamin B12 (Vitamin B12), which are important for nerves, etc.
Symptoms of neuropathy
Patients often experience pain and numbness. Pain can take many forms, such as:
- A stabbing pain in the body like an electric shock.
- Burning pain
- Cold pain like being hit by ice, tingling sensation
- A sharp, stabbing pain that feels like a needle prick.
- Itching or abnormal tactile sensations
These abnormal sensations may occur spontaneously or after stimulation. They range in intensity and frequency. Some patients may have mild, persistent pain, or experience severe, persistent pain.

Risk factors
Risk factors that cause symptoms of neuropathy include patients with underlying diseases or the above conditions that are the cause ( common causes of neuropathy ) , old age, which makes it easier for nerves to be injured and recover more slowly than younger patients.
How dangerous is neuropathy?
Neuropathy has a wide range of pain and symptoms, and is a chronic disease that can be detrimental to quality of life. In patients with severe and persistent pain, it can cause insomnia, loss of concentration, depression, anxiety, and loss of appetite.
Diagnosis
Initially, the doctor will make a diagnosis from the history, symptoms, underlying diseases and related causes. He will also perform a physical examination, especially examining the nervous system, the patient’s sensations, and examining the system from the likely related causes. Then, he will be able to diagnose the symptoms of neuropathy.
Further laboratory or imaging tests (eg, computed tomography, MRI) may be ordered in patients with complex or unclear etiologies.
Treatment methods
Treatment of neuropathy can be divided into two main groups: treatment to relieve symptoms and treatment according to the cause of neuropathy in each patient.
Treatment to relieve symptoms
Treatment for symptomatic relief: Medicines can only be prescribed by a doctor and are adjusted according to the symptoms in each patient.
- Pain relievers , NSAIDs or Opioids
- Pain relievers for neuropathic pain, TCAs and Calcium channel blockers
- Topical medications such as patches or topical anesthetics for pain relief
- Rehabilitation medicine treatments such as nerve stimulators, transcutaneous electrical nerve stimulation, and physical therapy
Treatment according to cause
Treatment according to the cause of neuropathy in each patient
- In some cases, if the cause is treated, the symptoms of neuropathy can be significantly improved. Such as diseases that cause nerve compression, treated with surgery or physical therapy, some types of neuropathy that occur on their own or after certain infections, such as shingles (Postherpetic Neuralgia), etc.
- Some conditions may help to prevent the symptoms of neuropathy from getting worse because they are chronic diseases that have been around for a long time. The peripheral nerves have been damaged for a long time, such as poorly controlled diabetes. Controlling blood sugar may not help to improve the symptoms of neuropathy significantly but it helps to prevent the symptoms of neuropathy from getting worse. Or cerebrovascular disease, etc.
Protection
- Eat healthy food that is rich in vitamins and nutrients.
- Exercise regularly to strengthen your muscles, nervous system, and immune system.
- Avoid excessive repetitive behaviors.
This can lead to nerve compression syndrome, such as lifting heavy objects for a long time, standing or walking for a long time, or using one wrist too much. If necessary, it is recommended to change your posture frequently and stretch your body as well.
- In diabetic patients, it is recommended to control blood sugar levels through diet control and medication to maintain a good blood sugar level consistently before symptoms of neuropathy appear because it can prevent neuropathy from occurring.
- In patients with spontaneous neuropathy or after certain infections, such as shingles, it is recommended to see a doctor as soon as possible from the onset of symptoms, as specific medications will be more effective in patients who start medication early.
