I experienced the same thing a few days ago, and I am on a 200 mg test-E / week only, no oral.
I was driving to walmart when the tingling started, and when I was walking through the store my right hand would go numb for a few seconds at a time.
So I put my left hand and my right hand next to each other on the counter, and my right hand was more white than my left. I think it was receiving less blood.
The tingling and numbness went away after about five minutes, and the color returned to normal.
I was more stressed and agitated than normal that day, and may have caused my blood pressure to rise.
Maybe its a blood pressure thing? I really have no idea.
