Re: [RC] Broken leg pain - Bruce Weary

Dear Amber,
The residual post-fracture pain you still have is most likely coming
from the periosteum, which is the membrane that "coats" our bones. It is
very richly
supplied with nerve endings and blood vessels, and is responsible for
most of the pain associated with a fracture. The
inner core of our bones is actually not very pain sensitive. For
example, a person can have bone cancer deep inside
a bone, but feel little or no pain until it eats into the periosteum.
By definition, when a fracture occurs, the periosteum is torn, and must
heal, as well as the bone. Sometimes,
the periosteum can heal with fibrous scar tissue, which can adhere to
the nerve endings, and cause future pain,
especially after weight bearing.  There are also nerve endings known as
"baroreceptors" that sense changes in pressure--even
changes in barometric pressure--when they are irritated. Like those that
accompany weather change. When granny's knee used to tell her
it was going to rain, that's how she knew. That mechanism could also be
causing some of your pain. Local heat to the
area and massage to your pain tolerance may help.  Good Luck, Bruce Weary DC
