Ya I have cholestasis it turns out
This makes more sense with how far along you are...cholestasis of pregnancy. Google it.
I had the same thing! I wasn't swollen though or as far along. I was around 14 weeks when it started and my doctors couldn't figure it out for a while. My palms and soles would get the itchiest at night. At first they thought it was a fungus, but it didn't make sense for it to be on my hands. Then they thought it was body lice (or mites) from our dog. We had her tested 3 times and even gave her meds just in case. Finally I came across something online about high levels of estrogen causing it. I found out a few weeks later I was pregnant with a little girl so it all made sense. It went away on its own in a few weeks once my hormones leveled out.
