Brain Protein Promotes Maintenance of Chronic Pain:

A protein called RGS4 (Regulator of G protein signaling 4) plays a prominent role in the maintenance of long-term pain states and may serve as a promising new target for the treatment of chronic pain conditions, according to research conducted at the Icahn School of Medicine at Mount Sinai and published in print October 16, in The Journal of Neuroscience.

The discovery may help doctors stop acute pain from progressing into chronic pain, a condition in which patients experience not just pain, but a number of debilitating symptoms ranging from sensory deficits to depression and loss of motivation. The transition from acute to chronic (pathological) pain is accompanied by numerous adaptations in immune, glial, and neuronal cells, many of which are still not well understood. As a result, currently available medications for neuropathic or chronic inflammatory pain show limited efficacy and major side effects. Commonly administered opioids provide temporary alleviation of some pain symptoms, but carry serious risks like addiction in the context of long-term treatment for chronic pain. Therefore, there is an imminent need for novel approaches towards the treatment of chronic pain and for the development of medications that disrupt pain states instead of simply alleviating symptoms.

"Our research reveals that RGS4 actions contribute to the transition from acute and sub-acute pain to pathological pain states and to the maintenance of pain," says Venetia Zachariou, PhD, Professor in the Nash Family Department of Neuroscience, the Department of Pharmacological Sciences and The Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai. "Because chronic pain states affect numerous neurochemical processes and single-target drugs are unlikely to work, it's exciting to have discovered a multifunctional protein that can be targeted to disrupt the maintenance of pain."

What possible survival benefit can there be for having a pathway to actively maintain chronic pain?

    Hopefully these guys are on to something, because neuropathy sucks!

    After five years in an opiod stupor, I weaned off of them (six years ago) and with self-hypnosis, fasting and meditation learned to not notice it much. Even so, it is exhausting and seriously restricts activity and quality of life. About once a year, I treat myself to an opiod day so I can remember what life feels like for those who don't suffer neuropathy.

    A better blocker would be a God-send.

      oops...

      read opiod -> opioid

      Damn! now the fingers are failing.

    What possible survival benefit can there be for having a pathway to actively maintain chronic pain?

    Looking for solution of this problem, let me shift the paradigm a bit for a moment:
    What possible survival benefit can there be for having a pathway to actively maintain an error log?

    Well, an understanding is now obvious: it motivates to behavioral change for the purpose of remove causal source of error.

    You can now backport this solution to the original pain problem.

      http://painexhibit.org/en/pain-and-art/ [painexhibit.org]

      Art is far more effective at communicating the pain experience than words. The pain experience goes beyond the actual occurrence of physical pain and encompasses the entirety of one’s life. This experience can be both negative and positive.

      The negative pain experience can include multiple surgeries, painful treatments, using different medications which produce unpleasant side effects, the failing of relationships, feelings of isolation and being trapped, poor self-image, depression, insomnia, frustration in trying to find quality medical treatment, and battles with insurance companies and lawyers. Since chronic pain frequently cannot be seen, unlike a broken arm, many with pain are not believed by doctors, colleagues, friends and family. This lack of belief is especially difficult for those living with pain.

      Although no person would ever volunteer to have chronic pain, the pain experience can impact one’s life in positive ways. “What does not kill you makes you stronger,” is an applicable quote. It is not unusual for people with chronic pain to develop greater inner strength, and to become more introspective which leads to increased self-understanding. Chronic pain may change the course of one’s life and result in a more satisfying path. It is not unusual for those in pain to begin the pursuit of a spiritual path which can greatly enhance life.

      While minor compared to some, my chronic neck pain has led to introspection, but not through any type of organized religion. And, yes, I can also *be* a pain in the neck...

      At first I thought most people were too dumb to understand pain is a message telling you what you are doing wrong.

      Now I'm pretty sure people know this, but they don't give a shit and don't want to change so please pass the pills to help me ignore the consequences of my actions.

    RGS4 inhibitors already exist - https://www.sigmaaldrich.com/catalog/product/mm/538498?lang=en®ion=US [sigmaaldrich.com]
    But at $100 USD per 10mg dose, I don't think I can afford it without health insurance paying for most of it!

    There has always been a solution to pain on earth, it is called the poppy plant, and the united states government and associated mucky mucks have a near total monopoly on its production, but same entity declares it completely illegal and covertly traffics the raw material because it turns out the cure for pain has an even better markup % than oil.

    As to the question of the evolutionary purpose to a pain signal not deactivating, I think in evolution things that cause beings to be more cautious probably have an evolutionary basis, and my chronic pain totally reminds me to avoid anything resembling a football game or hand to hand combat.

    I think also turning things on in the body is easier than turning them off. Meditation has helped with chronic pain, and time in general. I have seen in my life how I can get my body to turn off at least some kinds of inflammation.

    These people, like they have been doing for a while, are looking for a way to deactivate pain without giving any kind of pleasure and I find this pursuit insane and puritanical.

    What they want is a way to get people to grind themselves down to the bone working for other people's capital accumulation without noticing that their body is being destroyed and then eventually they will be discarded once they are ground down, after which time they will neither be able to work or afford fancy drugs to make backbreaking work feel like it is not backbreaking work.

    With dire implications for that one horse on the farm who just likes to work for the sake of his quality ethic and being a bro, thinking he's one day going to get to retire and enjoy some of the good life, when the second he stops working for whatever reason, he becomes totally useless to predatory capitalism and/or whatever totalitarian flavor.

    In the case of a writer/etc like me, by the time my fingers wear out all of my ideas will have been scraped off of the wires and the best parts simply incorporated and bastardized into the 'work' of those the cultural hegemony approves of after which point my fingers will be too broke to even think about writing up a legal prior art complaint. And getting the cia's entertainment lawyer to admit they got the plot for avengers 10 from your email will be a real trick.

    Oh how I hate living in a world run by garbage people.
