Help, legs buckling underneath me then shaking uncontrollably..
Not very sure what is wrong with me, but very scared. I used to be a very fit athlete and would do a lot of training, running nearly every day, sometimes cycling swimming and running all in one day. However something began to start happening which has ruined everything, when I ran my legs would just stop, it was so weird, I would have to walk as they would simple not physically go. This got worse and worse, initially I thought it might have been an exhaustion thing or blood sugar thing, so started paying attention to my diet to eliminate this possibility. This got progressively worse, I had to stop running. Now even walking up the stairs quickly triggers it off, after attempting light exercise on an exercise bike today, my legs stopped after 5 minutes, when I got off I could not walk and literally flopped to the floor, my legs then started shaking. I am really scared that I have something very wrong with me. I had to lay down for half an hour before attempting to walk again. An hour and a half later I am fine and moving around but I am worried that I will never be able to exercise again or it might get worse and will happen to me when I am just doing normal things like shopping etc. Anyone got any ideas what it could be?
