Hi Guys,
That's really kind. Thank you! I'll let her know my geek friends are passing on their best wishes.

Hi Richard,
They confirmed it is nerve damage. They are trying to reduce the swelling around the nerve route with the steroids. I forget which exact one they are using. They also had her on a very high dose of something else that also eased her headaches and sore hip. She's in the wean-off stages of that treatment. I think there is only one injection left. As you can imagine, they are uncomfortable and they also cause dizziness. I have to drive her. It's a good thing I'm retired!

Hi Destroyer OS,
Thanks, I'll pass that information on to her.

Walking is still a problem for her due to the unsteadiness (dizzy, but not the spinning kind.)

Hi Richard,
The type that sounds the closest to her situation is "Ménière's disease (a disorder of the inner ear that can affect hearing and balance)". That was clipped from that page you linked (thank you). Her other ear has a birth defect that causes a lack of high frequency information. It wouldn't have been so bad if it was that ear that was affected.

I've been dizzy (unsteady, not spinning) since a car accident in 2005. This accident is also why I'm retired. You get used to being dizzy and I rarely fall these days. It's a matter of concentration. Like anything else, it happened and there doesn't appear to be a cure. Anita is resigned to getting use to this and dealing with it. It's not like there are any other options open.

I merely pointed out that I was suprised that very few people (this being a DIY forum I meant DIY types) used this.

Tom Christiansen is doing some work with THAT chips

Chris I wish the best for your wife. :xfingers:
A friend went through this two years ago. The first 6 months were difficult. Now he has recovered 80%.
He is a doctor close to retirement. Doctors make for the worst patients (they know what is going on and adopt in their mind the worst scenario)

We had an adage that, on average, one's thesis is read .9 times, including the author.
My experience is that the number of mistakes found on each reading rapidly converges to zero, but not because there are no more mistakes. My 'internal examiner' was one of those forensic proof-readers, but even he failed to spot a few mistakes which made it through the whole process. A few of these were mistakes you could only find by repeating my calculations, although fortunately they didn't change the conclusions. One mistake was a 20dB error in the power levels in a table/graph - I forgot I had an attenuator in line. This was found a year or two later by some reading the online version and attempting to understand it.

So, a few mistakes in a thesis are likely. My concern about the McGill thesis is that the mistakes are mostly ones which should have been spotted, and I only looked closely at one chapter. He had to swap supervisor part way through the work, so it could be that the original Prof knew about electronics but the replacement did not. Obviously a lot of work went into it, but the difference between a Master's thesis and a PhD thesis is meant to be more than just length.

Oh agreed entirely, my eyes still go bleary *thinking* about writing it. I was just making light of the situation about the rigors of one's dissertation. Although my MS advisor was maniacal about proofreading, I am 99% sure no one read my Ph.D dissertation (different uni/different committee). At least among my friends/colleagues, the thesis itself could have been a 150 pages of "Lorem Ipsum" and no one would have batted an eye, as long as one's journal submissions were solid. As such, I'm loathe to know the number of mistakes in my thesis, although I did go through the EM a few times from Maxwell* to ensure I didn't mess that up, and wanted to make absolutely sure that my sims weren't total GIGO.

*My EM learning matches what JNeutron wrote somewhere recently, in that it was a year+ worth of material condensed into a quarter. I did miserably in it (by my estimation at least) and probably did better than most.
 
Guys, I do *really* *really* wish that giving medical advice/anecdote was as verboten as political/religion here. Tread very lightly, please, because it's so easy to get it very very wrong and lead someone in the opposite direction (or distract someone from seeking the medical help they really need).

Chris/Anatech -- wishing your family the best. That's awful to hear, but hope the nerve damage is very limited and she restores most of her ability when the swelling abates.
 
People can receive bad or maybe good advice from many different sources. If not, here then somewhere else. What someone does probably depends more on whether they have health care coverage, can afford to see a doctor, and or are of a type that finds alternative medicine attractive. If no medical suggestion could be given here, then presumably advising to go see a doctor immediately! would also be prohibited. Don't see how that would necessarily be a good thing.
 
Mark, think earnestly about what you wrote and think about the quality of the recommendations being given thus far. We can say the same thing about basically any topic, but, in theory, this site does try to maintain higher quality information. The lounge is certainly way more "Wild West", but I'd argue that the mods/user base's domain of expertise is NOT in medicine, and the checks and balances is not there. The consequences with a misstep is very very real.
 
What about when somebody has already been to one or more doctors, has received a diagnosis, they were not told the condition was serious or life threatening, and the doctor says there isn't much we can do, or, you could try some supplements some of our patients find helpful, or the doctor has tried a few things and nothing is helping?

Regarding herbal remedies, homeopathy, and similar things, obviously they should not be used instead of seeking professional medical advice first, assuming people have access to that. Here in the US, there are still many people without healthcare coverage who may agonize over the costs of seeing a doctor, even worse if expensive tests may need to be done. I am aware of such people who opted not to see a doctor perhaps in part because nobody emphatically told them they should do so without delay.

You obviously take the advice of members of a diy audio site who have no knowledge of your background/history nor much substance to what they say.

There has to be a balance against the entirety of patient autonomy and due diligence, but even with the number of errors medical professionals make, they do way way way better than us lay people.
 
Look, there has to be a balance between freedom of speech and the risk of harm. There is more to human morality than minimization of harm. I don't think there is evidence that people talking about their health problems online is a social problem of such magnitude that people have to prevented from talking about such things at all.
 
Until Walt Jung started his POOGE series on equipment modifications and upgrades, doing such things was not usually done. WJ did power supply upgrades, opamp upgrades, Cap upgrades, dc servo etc etc. Mods were done to CD players, amps, preamps - tube and SS. Since then, the DIY community started to grow and a healthy number of people do similar things plus more... ac line filtering etal. because of the POOGE series in particular got the word out that amps will 'sound' better/accurate doing those mods/upgrades, many have verified the results as being audible most of the time. All consumer and pro have included much of the mod ideas and concepts WJ initiated and promoted --- the result is a lot better sound. Thank you, Walt. <3

The series of POOGE articles in AA got me hooked on this madness, "Thanks" Walt

That balance is a difficult thing. I understand and appreciate both sides of this discussion, having lost someone who relied on "trusted" alternatives, ignoring sound medical advice which had extremely high success rates, and another who availed herself of every possible current medical procedure, to no avail.

The one who went alternative...could still be alive today, but then again.....there's free speech..

DPH is expressing caution, I agree with that.

Hi Richard,
Prednisone
Yes, that's it.

All,
Thanks all for your best wishes. I have a sister and mother that would attempt to heal Anita with crystals and other assorted rubbish. In our case we are quite immune to suggestions that are off the mark. Anita has accepted that it is a permanent condition and anything she gets back is bonus. A healthy outlook as far as I'm concerned.

After my accident, I've improved a lot past predictions. It's all about effort and determination. That and a realistic acceptance of one's condition and likely outcome. I'm sure that there are many stories like mine out there.

-Chris
