What is the Difference Between Paresthesia and Dysesthesia?
🆚 Go to Comparative Table 🆚Paresthesia and dysesthesia are both abnormal nerve sensations, but they differ in severity and underlying causes.
Paresthesia is usually painless and may be temporary or chronic. Common sensations associated with paresthesia include tingling, numbness, skin crawling, and itching. It is often caused by pressure placed on a nerve, such as carpal tunnel syndrome.
Dysesthesia is chronic and often painful, with sensations that can interfere with daily activities, sleep, and quality of life. Dysesthesia may be described as prickling, burning, stabbing, ice cold, electrical sensations, pain with only light touch, and cold feeling hot or hot feeling cold. It is caused by nerve damage and can be associated with conditions such as autoimmune disorders, multiple sclerosis, diabetes, Lyme disease, drug or alcohol withdrawal, peripheral neuropathies, certain types of stroke, and chemotherapy.
Both paresthesia and dysesthesia can be diagnosed based on the patient's medical history and a physical examination. Additional tests to diagnose the causes of these sensations may include nerve conduction studies, skin biopsy, cerebrospinal fluid (CSF) analysis, magnetic resonance imaging (MRI) of the brain and cervical spine, and X-rays of the cervical/thoracic spine. Treatment for paresthesia and dysesthesia depends on the cause and may include physiotherapy, medication, or addressing the underlying condition.
Comparative Table: Paresthesia vs Dysesthesia
Paresthesia and dysesthesia are both abnormal nerve sensations, but they differ in terms of their characteristics and causes. Here is a table highlighting the differences between the two:
| Feature | Paresthesia | Dysesthesia |
|---|---|---|
| Definition | Abnormal sensations or tingling in the body, often described as a "pins and needles" sensation | Abnormal and unpleasant sensations, often painful |
| Sensation Type | Numbness, tingling, skin crawling, itching | Prickling, burning, stabbing, ice cold, electrical sensations, pain with only light touch, cold feels hot or hot feels cold |
| Causes | Pressure placed on a nerve | Nerve damage |
| Severity | Usually painless, may be temporary or chronic | Chronic and often painful, sensations can interfere with daily activities, sleep, and quality of life |
| Diagnosis | Physical examination, nerve conduction studies, electromyography, imaging studies, blood tests | Physical examination, nerve conduction studies, electromyography, imaging studies, blood tests |
| Treatment | Depends on the underlying cause, may include medications, physical therapy, occupational therapy, or cognitive-behavioral therapy | Aims to manage the underlying cause and provide relief from the symptoms, may include medications, therapies, or addressing the underlying medical condition |
Paresthesia is typically painless and can be temporary or chronic, while dysesthesia is often painful and chronic, interfering with daily activities and quality of life. Paresthesia is caused by pressure placed on a nerve, whereas dysesthesia is caused by nerve damage.
