I went to go get tested and came out negative.

When I was pregnant I got extremely itchy in my 2nd and 3rd trimester. I scratched my back, chest, neck, and arms raw from the itchiness. Got tested and found out I had a potassium imbalance so I got put on a nasty pink medicine for the remainder of my pregnancy. It actually helped though. I'd say get checked just in case.

my back had been real itchy for the past week
