Pain mechanism

I always enjoy a good pain mechanism article. Here are some block quotes in bold from this one. Give it a read.

Over one-third of the world's population suffers from persistent or recurrent pain, costing the American public alone approximately $100 billion each year in health care, compensation, and litigation (1). Chronic pain is associated with conditions such as back injury, migraine headaches, arthritis, herpes zoster, diabetic neuropathy, temporomandibular joint syndrome, and cancer. Many of the currently available pain therapies are either inadequate or cause uncomfortable to deleterious side effects. Chronic pain results not just from the physical insult but also from a combination of physical, emotional, psychological, and social abnormalities. Because many pains persist after an insult is healed, the ongoing pain rather than the injury underlies the patient's disability. Untreated pain may become self-perpetuating because pain has immunosuppressive effects that leave patients susceptible to subsequent diseases. It is now clear that if we can effectively treat the pain despite the underlying cause, it will be possible for patients to regain normal functioning. The key to more successful pain treatment is to understand the mechanisms that generate and maintain chronic pain. Mechanisms of pain


Neuronal Plasticity


Plasticity is a term used to refer to changes that occur in the established nervous system. Changes in neuronal structure; connections between neurons; and alterations in the quantity and properties of neurotransmitters, receptors, and ion channels can ultimately result in increased functional activity of neurons in the pain pathway. Conversely, plasticity can decrease the body's own pain inhibitory systems, resulting ultimately in increased pain. Injury, inflammation, and disease can all cause neuronal plasticity and increased pain by means of increased excitatory or decreased inhibitory mechanisms. Plasticity can result in short-term changes that last minutes to hours, or long-term changes which may be permanent. Mechanisms of pain

100 Symptoms of Fibromyalgia

There was a site that had this and I had linked to it on Tumblr but it is gone. So I had to hunt down someone who found my post and posted the whole thing in a forum. Anyway it is around but I'm posting it here so I will not have to hunt it down to reference it. Now we all know the major symptoms are the wide-spread pain, but our pain isn't just muscle pain... it can be nerve types of pain as well, and the fatigue and the insomnia. And even among symptoms there are some far more frequent than others, but it should be said we have categories... like the cognitive dysfunction, which is a broad one that has more than one symptom and we often just say fibrofog. The insomnia... more than one sleeping disorder. So the list is interesting.




GENERAL
__ Fatigue, made worse by physical exertion or stress
__ Activity level decreased to less than 50% of pre-illness activity level
__ Recurrent flu-like illness
__ Sore throat
__ Hoarseness
__ Tender or swollen lymph nodes (glands), especiall…

When I say I am good

When people ask me how I am feeling 99% of the time I am lying. I often say 'not bad', because I feel it is slightly more honest than 'good' or 'fine'. Got sick of fine. Anyway, I lie for many reasons. 



I'm having a good pain day: They happen and I'll say that I'm good, fine, not bad. I even feel like I can accomplish great things... in moderation. In which case, relatively speaking, for Me I am not actually lying. This is a Good pain day, it is Not Bad for me and I am Fine with it. I just don't want to explain: I just don't want to explain how crappy I feel and in which way I mean. Because I am tired of it. I just want to deal with it, without having to discuss it, mention it or have any sympathy expressed about it. Because it can be complicated. It may be a migraine with specific symptoms. Maybe it is a FM flare though. Or both. And then I have to explain what it is because most people think my migraines are the main issue but I could be FM…
