My extended family is selling a shared house, and this has required some work...especially cleaning. I have had ME/CFS for 14+ years now. There are flares, but I am fairly high functioning if I pace myself. On two occasions, several months apart, I have had both arms go numb for several days following a couple of hours of cleaning. I am really sensitive to heat, and I overheat easily. Someone told me these can be signs of MS, but I would like to know if other ME/CFS-ers experience this as well. Strangely, this doesn't set off a FM flare...those are distinct episodes. I end up needing several weeks to recuperate from a trip to deal with the house, but fortunately it is done, so I won't have to do this again.
