Researchers Find Main Source of Pain in Blood Vessels.
Researchers
have found the main source of pain in Fibromyalgia patients, and
contrary to what many believe, it does not stem from the brain. The
findings mark the end of a decades-old mystery about the disease, which
many doctors believed was conjured in patients’ imaginations. The
mystery of Fibromyalgia has left millions of sufferers searching for
hope in pain medications. Up until recently, many physicians thought
that the disease was “imaginary” or psychological, but scientists have
now revealed that the main source of pain stems from a most unlikely
place- excess blood vessels in the hand, legs and foot.
The
discovery may lead to new treatments and perhaps even a total cure in
the future, bringing relief to as many as 5 million Americans thought to
have the disease. To solve the Fibromyalgia mystery, researchers zeroed
in on the skin from the hand of one patient who had a lack of the
sensory nerve fibers, causing a reduced reaction to pain. They then took
skin samples from the hands of Fibromyalgia patients and were surprised
to find an extremely excessive amount of a particular type of nerve
fiber called arteriole-venule (AV) shunts.
Up until this point
scientists had thought that these fibers were only responsible for
regulating blood flow, and did not play any role in pain sensation, but
now they’ve discovered that there is a direct link between these nerves
and the widespread body pain that Fibromyalgia sufferers feel.
The
breakthrough also could solve the lingering question of why many
sufferers have extremely painful hands and foot as well as other “tender
points” throughout the body, and why cold weather seems to aggravate
the symptoms. In addition to feeling widespread deep tissue pain, many
Fibromyalgia patients also suffer from debilitating fatigue.
Neuroscientist
Dr. Frank L. Rice explained: “We previously thought that these nerve
endings were only involved in regulating blood flow at a subconscious
level, yet here we had evidences that the blood vessel endings could
also contribute to our conscious sense of touch… and also pain,” Rice
said. “This mismanaged blood flow could be the source of muscular pain
and achiness, and the sense of fatigue which are thought to be due to a
build-up of lactic acid and low levels of inflammation fibromyalgia
patients. This, in turn, could contribute to the hyperactivity in the
brain.”
Current treatments for the disease have not brought
complete relief to the millions of sufferers. Therapies include narcotic
pain medicines; anti-seizure drugs, anti-depressants and even simple
advice such as “get more sleep and exercise regularly.” Now that the
cause of Fibromyalgia has been pinpointed, patients are looking forward
to an eventual cure. Other expressed frustration about how much they had
suffered already:
“When are they ever going to figure out that
things are never “all in your head?” said one commenter. “Whenever
something doesn’t fit in their tiny little understanding, they belittle
the patient and tell them they are crazy. People have suffered through
this since they were invented. Prescribing SSRIs for everything is not
the answer any more than a lobotomy or hysterectomy was.”
The
announcement has the potential to unlock better future treatments and
undoubtedly has patients all over the world rejoicing that the mystery
of Fibromyalgia has finally been solved.
