I have 3 smallish Toothpick Cacti (I love them because they are so unique looking) but have accidentally stabbed myself a couple of times. This last time, I had to pull a "toothpick"/barb out of my palm - in the fleshy part below my thumb. It turned black & blue in less than 1/2 an hour. Can't seem to get it all out (& believe me, I've tried!) & at the same time I have been feeling very lethargic...Any chance this could be caused by the barb?
