I had been using the bench press quite a bit and my arms would go numb sometimes when I was sleeping. I would get up and have to wait until I could use them before doing my daily tasks.I started my leg workouts when I figured out how bad it was. So now I want to try oxygen therapy as my veins are blue and science will show red blood cells carry oxygen. Long story short my shoulders are blue and I am going to try oxygen to fix it.
