I am new too! The numbness in the arms and legs is one of the symptoms I have at the start of a panic attack. Do you think you might be depressed? I would go get a total physical with your doctor and describe your symptoms. The panic attacks I have can last for hours, I actually totaled a car about 20 years ago because I had one while driving on a highway...not fun and they are no joke. Best wishes I hope you find an answer.
