I've been able to substantially cut down on the dizziness by adjusting my first rib. Adjustment techniques have been discussed elsewhere on these forums. You can search here, on google and youtube if you need more info.

I'm doing 3 sessions per day, 5 mins each. Yesterday I adjusted the angle to be a little deeper.

I have fewer symptoms all around, whether it's back pain or TOS, but it's a bit early to declare victory. Today is day 10.

I'm at about 60 degrees now, 6 minutes, 3 X per day. When I'm inverted, I feel stretching throughout my torso, waist muscles, back, ribs and neck.

This is the first angle that has given me elongation and loosening of the neck. Also, I seem to be getting less severe muscle spasms in my neck and ribs. My scm is less tight than before.

I can't really tell if the neck improvements are from the muscles being stretched, or from the pressure being taken off the nerves that enervate them. Or both. I guess it doesn't matter.

I was in better overall shape for my chiro appointment with regards to my neck and first rib. Also my pec minor was the best he's ever seen it (he does soft tissue work). My inversion is not at a full 90 degrees so my arms hang back relative to my body and my pec minors get stretched.

I still got some back pain the other day. My improvements so far are not 100%. I have all the same stuff, just dialed down.

The experiment continues, but so far, so good. It's been about 15 days.
