One of my kids had a horrible case and it was all over his wrists and the back of his hands. Also while it’s generally referred to as HFM it should be called HFMB, or hand, foot, mouth and butthole area.

I just had it and the spots felt like itchy pins and needles. Not painful if left alone but knocks and bumps were very painful. I could feel the tingling behind my index fingernails (you can lose finger and toenails some time after getting the virus, although it hasn’t happened yet). The whole of my back was similarly tingly. I didn’t get around to taking any pictures of my butthole area unfortunately.
