In my experience, most illness is a direct result of a certain entity (or entities) sucking the life out of the host not only creating ugly health problems but also completely draining the person. These are low vibratory parasites who operate in the "unseen" astral realm.
It is common to experience bodily aches and pains in the area of an entity attachment. These can feel like heart problems, organ failure, high blood pressure, energy depletion, bad eyesight, alcoholism, drug and porn addiction, inability to quit smoking, etc.
There is a myriad of entities that stay with a person and coax him or her to partake in the vices like smoking, drinking, drug abuse, porn, masturbation addiction, over-eating, etc., to name just a few.
Once removed from the client's energy structure, entity clearing is felt immediately, resulting in more freedom in the body, the disappearance of immediate aches and pains, increased energy, and elevated mood!
Clearing bad energy & aura clearing will have you feeling like yourself again! Spirit attachments, especially negative spirit attachment, are very common and is part of routine Entity Clearing when I work with clients online or in person.
