pain
"I have a rare neurological disease that causes extreme amount of pain everyday of my life.  My doctors have tried their very best to get my pain level that is tolerable without much luck.  I started going to a pain clinic where I was introduced to ketamine infusions by IV.  At first we did a weekly session with 45 minute infusions that changed my life.  I still was struggling with significant pain daily so the doctor decided to start doing 4 hour long infusions once a week.  I can't remember in the last decade that I was able to achieve a pain level less than a 5 on the pain scale. Plus it has helped with depression and PTSD among other positive effects.  Yes it makes you feel pretty out of it but I can start living life again."
