ITCHY!!!

My whole body is itchy, and I am sick of scratching.

Where to start, my chin, above my breast, the tops of my feet, behind my knees, butt cheecks, lower back, the small of my back, my face.

The only part not itchy is my fore arms where I am covered in hives!!!

HELP!!!!

What can I do???? Should I go and see the doctor??? Please someone
