Hey Daisy I have M.E and I do very gentle walking, how bad is your FM? Sometimes on a good day, I can manage to do anything 20 mins up to an hour (on a good day I try to go somewhere nice like the woods) , depending on the weather, as cold and wet makes my legs terrible. On bad days I try and force myself to do a small amount of walking, but sometimes only manage 5-10 mins (around the block usually)but I have to use two sticks, to help me on these days, and sometimes I get away with one stick and holding on to my partner.
I have considered getting a tread mill for my bad days so I can walk inside where its warmer, as warmth is defo affecting how well I feel, cold makes me feel awful. Could you do anything at home, like walk around the house?
