Patients Concern
Disease/Condition Glossary
Neuropathic Pain: It is a nervous disorder that occurs due to nerve damage caused by chronic progressive nerve disease, limb amputation, diabetes, or infection or injury. The pain could be intermittent or continuous, felt as a prickling, stabbing, tingling, or burning sensation. A feeling of numbness and loss of senses is also common with neuropathic pain. Usually, the body sends the pain signals when there is an injury, but with neuropathic pain, the pain that is not triggered by an injury, the body sends the pain signals. Symptoms include untriggered pain, unpleasant feeling, shooting, burning, or stabbing pain, difficulty resting or sleeping, pain caused by events that are usually not painful.
Epilepsy: is a sudden rush of electricity in the brain. It is a disorder of the nervous system which occurs due to disturbed nerve cell activity in the brain. Seizures are of two types: generalized and partial seizures. Generalized seizures affect the entire brain, whereas partial seizures affect only a part of the brain. Seizures can cause uncontrollable muscle twitches and spasms. Stronger seizures may cause people to become confused or unconscious. Possible causes include high fever, trauma, genetic disorder, brain injury, or stroke.
FAQs
Gabapentin is an anticonvulsant drug. In epilepsy, it works by stopping seizures by reducing the abnormal electrical activity in the brain. In nerve pain, it interferes with pain messages travelling through the brain and down the spine to block pain.
It is unsafe to consume alcohol since it may worsen the side effects like dizziness and drowsiness.
