Good evening @kzeiss, I am very concerned about your son. I have some kidney issues and know what it means when you have a syndrome of pain. Unfortunately, I am not a medication person either. I have been called the "pain warrior". I do think that our body accepts and tolerates a certain amount of consistent pain. For excruciating pain, I use medical cannabis and have done that for several years.
In fact, at this point, my chronic pain is managed totally by tinctures and topicals. I am happy to share additional information. I just need to know your son's age and his location.
