Yesterday and today, my arms had been itching so bad that is so annoying.

It started with my ring finger, I scratched it before I went to bed then it just kept on getting worse. And now, before bed again, my whole arm is itching.

It’s not swollen or anything, just obnoxiously itchy. Is it normal? Should I seek medical attention if it continues on? I feel like the GP would just embarrass me and say there’s nothing wrong and that it could just be allergies....
