I have had MS for 37 years now in the last 7 years my legs given out. The first time I was across a street in a near by town. lady was waiting a the lights with a RCMP behind her. She helped me get up with police man to. She took me home. Asked if I had MS this happened to her husband. I let this pass me by. Then about 3 years later my legs gave out when I was walking on a treadmill. I let that episode go. Now this summer I was swimming in a near b lake as I was coming out with my wife they gave out again. She me out with great difficulty. Now 2 days ago it happened again. I was doing a little job outside went to get the mail 3 blocks up and back. My walking was getting very hard. I could only take 2 steps at a time. By the time I got off the side walk to go up slight incline to get to the railing my legs gave out completely. I laid in the snow wondering what to since my wife was not home. I mange to get on bum and to the railing. With great difficulty I managed to stand up. I hobbled into the house. Has any with MS had this happened to them. Just wondering
