oh, this is on my top 5 most annoying pg symptoms.
I've had it BAD during all of my pregnancies, and, TBH, after my last pg, I was still experiencing it sometimes non pg
You asked about it as a pg symptoms? Well, I know the typical wisdom is that it usually starts later- but, seriously, I got my BFP and went "oh! that's why my legs have been so annoying this week!"
I can't find any good info on why it is worse in pg. I've heard hormonal theories, increased nutrient demands, and, for me, there's a huge ironic tie to it being more severe when I'm not sleeping deeply, so more tired (and then RLS gets worse and I can't sleep deeply
). I wonder if, since pg women have more sleep interruptions, if that is a part of it?
You mentioned being unusually tired- have you noticed a correlation for yourself between being over-tired and having bad RLS? (tho maybe you are tired as a pg symptom.)
Anyway, hope you can find good ways to deal with it- annoying problem whether pg or not. Calf stretching before bed, epsom salts and cal/mag do wonders for me.
