So yesterday I was sitting on my neighbors porch and I went to go by my house area cause my neice was in the little ally between two houses and when I was walking back to the neighbors I suddenly fell onto my knees I got right back up. It felt like my legs gave up on me when I fell it was really weird and thafs the first time anything like this has happened should I be worried about it or what? I've been overthinking this alot ever sense it happened.
