Rob, If you were old enough you'd remember a song by Jacqus Brel called Carrousel.
At the end of dialysis the tech took my temp, twice. He then informed me and the nurse that I was running a fever. The nurse said that the machine temp was just set too high, no worries. It is now 6 hours later and I still have a fever. Dang, they did a good job warming my blood.
I guess you should try his thigh next cariad, so if he jumps, the needle will go in further
