Oh yes the wet patches for me are the craziest alongside the marching ants lol. I have even gone to the toilet thinking i have wet myself (which I must say i do sometimes the joys of either being an old lady or MS). The water or wet going down the back of the legs nice one oh one of the others is the stinging bees on my legs even to the point i have stripped off my trousers to see where the beastie is and slap it one, and sadly nothing there, not even a red mark.
Oh and the invisible nudging. Thats a good one. I sometimes when i am upright even holding onto something which i usually am, feel like someone is behind me, and nudging the back of my leg usually the shin. I always turn around to see if its my dog or a cat and nothing will be there. Ah well weird things happen to the best of people. x
