Since you are a VK user for quite some time, can you answer which Cosmic serums would be helpful in this case.
Maybe you can type KIDNEY on litairian website and see what comes up. You need not know about the disease completely when you have VK, you can still choose energies.
Do you know any technique with VK to energise a particular organ to revitalise it?
Regarding your 2nd question i will answer you with my experiences , but i want you to come up with healing possibilities
