I know that this is an incredibly odd questions, but are there any drugs that simulate chronic pain, or constant pain over a short-moderate duration of time that does not cause any actual health issues?
I have known a couple of people with chronic pain disorders that can often get quite bad. I want to get an experience of what their daily experience is like, without self maiming or actively harming my physical body. Is there anything like this that is known, or has medicine never gone far enough in this direction to make it possible?
