Leg pains

Hey, ladies! So I’m 36 weeks today and yesterday started having sharp pain down the outside of my lower legs (mostly my right leg but the left also). I asked my husband to rub it last night but didn’t get any relief—he mentioned he could feel the fluid buildup in my leg. I have an appointment today so I’m going to mention it then but anyone else feeling this? I’m assuming it’s just from water retention and poor circulation since it’s both legs but I don’t remember this from my other two pregnancies. Anything helped for relief?
