Noticed this sore/bump and now my whole body is itching?

Well after my shower tonight I noticed this sore/bump on the side of my stomach. It's kind of sensitive but it's not itchy itself. Now I'm laying in bed and my whole body is itchy... my arms, stomach, back, feet, neck. Everywhere. Is this normal towards the end? I'm 34 weeks + 3.
