Remember this: Doctors will always do whatever they need to to cover their butts. One time my blood work came back slightly anemic... scared the crap outta me! I had to go back for 2 subsequent blood panels, both of which were normal. Prickly sensations in the legs could be anything from restless leg syndrome, to aggravation from shoes, to irritation from a new moisturizing lotion or laundry soap, to a pinched nerve in your low back. They are simply covering all bases, and helping to put your mind at ease. I know that waiting for test results is hell, so tomorrow, call the specialist's office and tell them, "I hate to be a pest, but I have terrible health anxiety... can you please tell me if the test results are in, and may I speak with a nurse?" Don't be shy, just try to have a nurse call you back so you can discuss your fears with him/her. God Bless!
