Help?

I randomly just got extreme swelling in my left leg and over the right side of my butt/hip.

I keep hearing if I get random swelling I should seek a doctor or ER immediately.

I haven't done anything to hurt it either. I literally have been doing normal stuff. Light house work and sitting in bed. But now my toes are sausages and my ankle to my calf are taught, and almost purpling like I busted capillaries. Not a lot just in a few spots.

I'm even getting dimples. And I think my right is starting to swell.

Should I go to ER?
