I feel as though I have had my rights as a woman taken from me, through no fault of my own'
Answer: Probably permanent, nerves regenerate at the rate of 1/8 of an inch per month under optimum conditions, so there is a chance depending on how far the nerve has to grow.
Nerve Damage [posted 1/6/99]
Question: What is the answer to this question? Without the politics of research
dollars, is it true that if nerves have not been severed will re-grow at about the rate of
1 mm per week, or have I been misled? Also is it possible to maintain muscle were there is
severe nerve damage by doing exercises?
Answer: Nerves can re-grow, but currently only thought to be the small
nerves at the end of the nerve process. There has recently been published information
using nerve growth factors, which may invalidate all our previous information on nerve
regeneration. In general, the central nerves (brain, spine, etc) are not thought to
regenerate. The peripheral nerves can re-grow new endplate processes. If the cell nucleus
is damaged, there appears to be no re-growth. If the cell nucleus is intact, there can be
growth in some circumstances.
Numbness [posted 8/7/98]
Question: In Feb. I began to experience numbness along the right side of my face,
which then radiated to my arm and leg. Consulted physician who ordered an MRI which came
back normal. Referred to neurologist who suggested atypical migraines and prescribed
verapomil - this did not help. Symptons lasted several weeks, then subsided. Returned
approximately six weeks later, lasted for two-three weeks, then subsided again. Now, after
three months of relief, the numbness is back, this time worse than ever. Numbness subsides
for a few hours then returns. I am not experiencing any other symptoms besides allergies
and occasional migraines which are treated successfully with zomeg. Always the numbness
begins the week before onset of menstruation, perhaps there is a connection? My
neurologist seemed content the last time the numbness went away and did not look into the
matter further. It is affecting my work and my life. Can anyone please help?
Answer: Have you had nerve conduction studies of the affected parts of
the arm/leg? This might help. Also, if it seems period related, try a couple of months of
birth control pills to alter your cycle and see if this helps to pin down the initiating
Loss of Feeling in Face [posted
Question: I have had a numb feeling in the right side of my face for over a month.
It starts in the corner of my eye next to my nose down into my cheek, the right side of my
lip and two of my front teeth. My family doctor thought it was a sinus problem but it has
not cleared up. My face feels like I have had a deading shot but I have not. There is no
sign of any problem just by looking at my face. I am a 43 year old white female.
Answer: You'll need a CT of your head and sinus to ensure that the nerve is not
impaired as it leaves under your eye. This is a clear peripheral nerve problem, finding
the specific spot that the nerve is being impaired will be harder - keep pressing on this.
Sciatic Nerve Damage [posted
Question: What are the ramifications of an IM injection into the sciatic nerve?
Prognosis? I only seem to find a sentence here or there. Pain is a factor. Muscle atrophy?
What happens to the nerve?
Answer: It depends a great deal on how much was injected and if in the center of
the nerve or the periphery. The variation from injection to injection error is
significant. Consequently, predicting the long term/short term damage is impossible. If
the nerve is significantly damaged muscle atrophy will result. This would be uncommon.
However, the volume injected and the site of injection would make major differences.
Regeneration of Nerves
Question: Is it possible for nerves to regenerate? If so, or if not, why?
Answer: A lot of research is ongoing in organ and nerve development and fetal
differentiation. Understand this issue would probably lead to different "growth"
factors which would lead to both organ and nerve regeneration/development. Again, this is
limited by lack of Federal Research Dollars.
