Have a stress ball that is soft and squeze or grab ice and hold in you palm of one hand and hold tightly that way your won't be hurting yourself permintly but get that cold sensation tingerling up your arms. Did the elastic band unfortally I pulled it too far that it snapped and ouch. Also sometime I use red crappy eye liner with out hurt I draw loads of lines down my arm. You still get a tiny feeling when drawing likes on your arms. If you have something sharp on you that you use, my advice is to get rid of it now. If won't help you only make things worse. I'm not going to give in! (again)
