I'm currently working a lot with the solar plexus chakra, I've always considered it to be the third chakra. In other words, right below the rib cage at the center above the gut.

I think that it has to do with personal boundaries, and I find it is effective to keep myself centered in it in conversations, to build on personal power and freedom. The feeling of I am can be felt stronger and clearer which is a foundation for well-being.

I can recognize some of the symptoms you've described, aunt clair, especially those about spinning slow.
