i have been involuntarily tightening the muscles in my body. for the last couple years. I find myself stiffening my legs, my arms, my tonguehips , neck, pretty much everything, but not all at once necessarily. then i relax the muscles when i notice i am stiffening my muscles...... my tongue also stiffens and goes to the roof of my mouth, so much so that it puts my teeth grooves on the sides of my tonge which i see when i wake up .... this stiffening happens any time of the day we d have neurological problems in family history i also was in accident and had mild concussion and took pain and sleep mediations it all seemed to start after that occurance, slowly for the last ten years about
