Can anxiety cause tingling in arms hands and feet? i was diagnosed with anxiety recently. i'm really worried about this being something serious

Yes: sounds like you are anxious about being anxious. Anxiety can cause a multitude of differing physical symptoms. Best thing to do is see a psychiatrist to learn treatment options and likely seek a therapist to discuss coping mechanisms and managing and dealing with anxiety. a good book is called the anxiety and phobia workbook which you can search for on amazon.
