As of the past couple of weeks, my walking has been feeling odd. Sometimes when I walk, my legs will feel like they are light and almost floating and it will become hard for me to walk without falling down. I'll feel like I'm about to fall. I don't feel lightheaded with it, I just feel like my legs will give out. They spasm and squeeze and feel weak. Sometimes, parts of my legs will feel like they are "crying", so to speak, there's no other way to describe it. I'm scared because so far, I have no idea what the hell this is. It usually goes on in my calf to the middle of my knee, sometimes throughout my leg. It makes me have to sit down [and sometimes I get leg pain sitting down]! Anyone deal with any thing like this?
