Most of our issues are held in our chakras in the etheric dimension. These issues create/attract dark energy through a process I don't understand.
This dark energy generally creates excess tension which in either the short or long term can cause painful stimulation of nerves.
Release of the issues will release the pain and any associated problems.
There is no primary chakra in the lower abdomen. However, it is extremely common to feel pain around the Hara.
When do you feel it? Does anything make it feel better or worse?
Chakra pain does exist, as I know only too well. But it's rare.
