Awareness in the body : ticklish/tingling feeling I'm trying to anchor my awareness while sitting at the desk.

When bringing awareness to the body , I'm getting a tickling/tingling in the body .  So to make it bearable I'm trying to move attention to different body parts and it keeps following too.  So unable to hold awareness in the body for a long time.  Is there any advice/guide on this ?
Relax your facial muscles &amp; take an out-breath or let go of some out-breathes.

In your efforts to anchor awareness, it sounds like you are suppressing the (mental) tension stored in your physical body (which will arise into your awareness if meditating). 

Balance your effort. At regular intervals, take your foot off the accelerator; ease off the throttle.
