Neurological symptoms and urgent warning signs
Memory changes, tingling, sleep problems and weakness have different possible causes. They should not be grouped under a single diagnosis or a promise to improve nerve function.
Possible stroke is an emergency
Sudden face drooping, arm weakness or speech difficulty can be signs of stroke. Call 911 immediately for suspected stroke. Do not wait for a wellness appointment, massage or online consultation.
