Yes i get those..I just had one in my thumb last night : ) I have them in my arms sometimes too in a very small area...Its hard when its the back of my left arm...there i go worrying its a heart attack...Ive had them in my ankle and in the bottoms of my feet as well. Of course i cant say for sure its a lyme symptom..but i have lyme and as far as i know nothing else...hope this makes you feel a little less alone with this symptom :)
