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.

May you have peace and ease.
Chris

@kzeiss,
I am concerned about your son's excruciating pain and that you have mentioned his high tolerance for it. Pain that is associated with a kidney condition and end stage kidney disease can be serious. I have searched this morning, and found this information on Mayo Clinic Patient Care & Health Information > Diseases & Conditions.
Pain -
"You might be able to control the pain of polycystic kidney disease with over-the-counter medications containing acetaminophen. For some people, however, the pain is more severe and constant. Your doctor might recommend a procedure using a needle to draw out cyst fluid and inject a medication (sclerosing agent) to shrink kidney cysts. Or you may need surgery to remove cysts if they're large enough to cause pressure and pain."...

@kzeiss, Has his pain increased suddenly? Is he in contact with his doctor about this? Is he a candidate for a future transplant?

@jolinda, @jennifer0726, @stephanierp, What has been your pain experience with PKD? How was it managed?
