Paresthesia can be chronic or transient wherein, transient paresthesia can be a symptom of a panic attack or hyperventilation syndrome while chronic paresthesia can be an outcome of nerve irritation, poor circulation, neuropathy, or several other causes and conditions. Contributions by experts from across the planet have been compiled in this book. The book aims to help the readers understand, treat and improve the lives of patients suffering from paresthesia.
