I was fine till a couple of months ago and was walking down the street and slipped a little bit. Now I am scared of going out just in case I slip. It got bad today as had to ask my dad to come with me and had to hold on to him.

my legs feel stiff and feel sick. Also can't go down ramps or anything like that or if been wet. I have concerts next year and also going to ireland and don't want to be worried about this

any tips or advice and what have I got?
