Awareness in the body : ticklish/tingling feeling
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.
