Restless leg syndrome?

I’m curious how those of you with restless leg syndrome would describe it?

I’m seeing my dr tomorrow because I want to rule out any clot possibility but I’ve been having this feeling in my legs but way more so in my right leg where it feels like a cramp or charley horse is coming on in my calf muscle but it never actually happens so as the day progresses my shin and the rest of my calf feel super full/stretched and achy. I have swelling (I’m almost 29weeks pregnant) but no difference between my two legs and nothing severe (I’m a teacher so I’m on my feet all day), no actual pain (just a full ache), no warmth or redness. Just this full crampy feeling that woke me up a few times last night.

I’ve been trying to pay attention more and i do think it gets worse throughout the day but it’s definitely there when I wake up in the morning too.
