After Botox injection 12 hours later I have tingling in hands/feet. Is this normal? Does it go away? Anything help?

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.
