GOLDEN SUNRISE
The slight headache with VS installation is a part of cleaning of negative energies at your place. So you felt a shift in energy.
If you have requested VS to synchronise, please note that VS is not an intentional healing tool like VK. It is completely self operational. And feeling better is also possibly due to change in energy through VS sensed by you.
Energy feeling with VK or VS varies from person to person and time to time. So it may not be the same for different people.
