Anyone else been shocked by a lightning cable?

I feel asleep this morning and apparently rolled onto my lightning cable. It was still plugged into the wall but not my phone. When I woke up I had this pain in my arm that felt like a bug bite. I soon realized there was a shape of a ligtning plug and cord in my arm. At the far end of the plug is what appears to be a burn along with a green mark. One of the pins on the cable has also been burned. Has anyone else gotten a little shock from one of these things? Picture attached.
