Thanks for your question.
To make them go away you need to get your anxiety treated. For treating anxiety you need to tell your doctor about these symptoms that you are having. Occasional xanax may be beneficial for some patients, but since you are having anxiety despite the medication your doctor may suggest a medication which is not addictive but needs to be taken daily such as a Selective serotonin re-uptake inhibitors or serotonin-specific reuptake inhibitors (SSRIs). Taking these medication will lessen your anxiety and all its peripheral manifestations will also decrease.
