Botox should never directly cause tingling in the hands and feet. On the other hand, anxiety and/or panic attacks can cause transient tingling in the hands and feet and it would not be unusual to have a little increase anxiety after a cosmetic treatment. Rarely tingling in hands and feet can be metabolic or from a neurologic injury in the peripheral nerves (not the cranial nerves of the face treated with Botox). I would recommend that if your symptoms persist, or recur your see a physician in person for a thorough history and exam.
