For several yrs. I have been experencing a sudden attack of squeezing sensation around my upper body. Under my armpits, chest and upper back. With numbness in both arms.It takes my breath away and only last about 20-30 seconds. I would say it happens approx. 4 times a month. I have had cervical spine surgery in the past and I sometimes think that it is an upper spinal problem but in the back of my mind I am thinking my heart...Before I spend all kinds of money on expensive test for either one, I am curious what anyone online might be thinking about this.
