MS symptoms, which have been so good lately, have been acting up all of December. Last month I was able to walk, lift & swim easily. Last few times, I haven't been able to complete 1 set, let alone my circuit. I'm tired again, I have to hold on while walking on the tread mill & am actually scared to go in water I can't stand in. Any exertion sets off muscle spasms. Back to square 1. Tomorrow's another day.
