Some of those symptoms I only had at my low point and don't have them now.
Yeah I used to think it was feeling my heartbeat everywhere but now what I think it is is the energy that is trapped wanting to be released. The reason why we feel it in the stomach so much and why I feel nauseous occasionally is because that is where the psoas muscle is which is directly tied to our emotions (knots in your stomach when nervous, etc). I'm sure a lot of people have tight hip flexors as well even if they may not be aware.
