Pain of the transformation?

[arch_enemy_94]

Hello, everyone. I want to ask a question about the pain I started feeling, but first of all, I have to mention that for a period of time, I have been practicing the eight-fold path of Astaroth. Recently, I have started feeling a quite strong pain on my back, to be more precise, in the sacral and lumbar zone. So is there any connection between these two facts or is it just a coincidence? 
Thank you all and Hail Our Brothers, the Demons and Our Parents, Lucifer and Lilith!!!
