About 2-3 months ago I noticed my legs and arms felt weaker, and when doing certain activities which before I could do with ease I find my legs and arms shaking. I've gone to the doctors and they haven't really given me anything conclusive. I don't have any history of anxiety, neither do I have any nerve or strength abnormalities. Everything is ok and I'm very healthy, yet I feel very weak and to describe it best it's like when you're trying to run in a dream but your legs aren't working properly. I'm asking as to whether anyone has expererienced this, because I feel it is hard to diagnose what I have or if I even have anything to diagnose, but is is definitely there. So if anyone has experienced this and is there anything I can do to help. It is worryingly me that it might be something which I'll just have to deal with for my life as there hasn't been any signs of improvement. Any suggestions would be appreciated.
