My doctor told me this is a common symptom in persons with excessive anxiety and anxiety disorders as well as patients who suffer from panic attacks. They often have pins and needles, tingles, buzzing, or other strange sensations in various parts of their bodies, especially the extremities. Since you noted that anxiety is a problem you have, you might mention this to whichever doctor/therapist/etc. you choose to regularly speak with concerning your other anxiety issues.
Hope that helps! Good luck!
