Hey everyone, so I wanna start this by saying that, my upper section of my right thigh has been known to ache and throb lightly for no reason that I can identify, for years now. But the other day when I went to stand up, something new happened. My leg literally wouldn't work and I fell straight to the floor. I'm 29 years old and 237 pounds (I stand 5' 11") and I've never had this happen to me before, nor heard of it happening to anyone else, all I know is the moment I tried putting weight on it, I collapsed completely. My leg didn't hurt as I did it, it wasn't numb or "asleep", I had no feeling of pins and needles, it just didn't work, I don't know how else to say it and it's so bizarre to me. When I tried to move it, it didn't move for a couple of seconds before finally it worked again and I was able to stand up. In the days since, I've felt random weakness in that same leg, specifically in my thigh, occasionally while walking and it's making me nervous, any idea what it might be? I can't afford to go see a doctor right now, should I be concerned?
