Well, you just answered your own question about the low blood pressure and
dizziness.
As to cough, it's a ruling out process and that's why the oncologist wants
him to take one every other day.

He's not on Lupron is he?  Lupron gave me an itchy-throat.   Other than
that, I have no idea.

Several months after Brachytherapy and IMRT, i also developed sudden
dizzy spell when going out for a walk. Had been on high doses of hytrin
(similar to flomax), and Diovan (angio-tensin). The dizzy spells were
caused by blood pressure dropping to low, by reducing the dosage, i am
fine now.

I also got dizzy from Flomax, but eventually I got used to it and
ceased to get dizzy.

As for the coughing, I didn't have that associated with brachytherapy
or Lupron, or any aspect of my prostate cancer treatment.

The coughing may be caused by a serious condition, though it
appears that Kent's doctors haven't been able to find it.

I'm not a doctor and my advice is purely based on my own
experience - no medical knowledge.  But given that caveat,
I'll go on to speculate that another possibility is that the throat
and upper respiratory tract are seriously irritated by the
coughing itself.  You cough to relieve a terrible irritation in
the throat, but the coughing actually makes the irritation worse
and it continues on and on.  I think that happens to me when
I get a bad sore throat.  The infection that caused the sore
throat seems to clear up, but I can keep coughing for weeks
afterward.

Kent might try the following:

Get the strongest cough lozenges available, the ones with
lots of menthol, benzocaine, dextromethorphan, etc.  Buy
several different brands and formulas and experiment to
find the one that works best.  Also get one of the sore throat
sprays the anaesthetize the throat with phenol.  In the U.S.
the popular brand name for that is "Chloraseptic".

Armed with this stuff, Kent should strive mightily to NOT
cough.  He should suck on a lozenge, spray his throat,
drink water, hold his breath, stare at the wall, whatever he
can do to not cough.  When he does cough, he should try
to control and stop it as quickly as possible.  He should
try very hard to not give in to fits of coughing.  He should
close his mouth and stifle the cough.

I found my coughing got worse at the end of a day.  If I went
to bed earlier I had a better chance to control it at night than
if I stayed up late when my throat was really irritated.

_Possibly_, this will give his irritated lungs and throat a
chance to heal.  _Possibly_, in a few days the urge will begin
to subside and in a week or two he'll be okay.

As I said before, I'm not a doctor.  Kent's problem may be
more serious than just irritated lungs and throat.  But it's
something to try, and you've got nothing to lose.

Best of luck,

They cannot find a reason for

My own experiences with unexplained chronic coughing may or may not
apply to Kent, but FWIW, here goes. A large increase in body weight
brought on by Lupron caused or contributed to an acid reflux problem
which irritated the throat and nasal passages. Sinus drainage also
irritated the throat. Now primed to react to most any additional
irritants (dust, cold air, heavy breathing, a cold) I frequently had
coughing episodes for little or no reason.

Numerous heart tests and breathing tests revealed nothing amiss.

Medication to control the acid reflux reduced my problem by about 75%,
and nasal decongestants have reduced it by another perhaps 20%. I have
not had to continue the decongestants, but do rely on medication for the
reflux, and the problems of a couple years of chronic coughs has been
silenced for about 9 months now. For me, the reflux had to be
eliminated, not just reduced. Good luck, chronic coughing is no fun and
I sure do not want to go there again. Bob C

When I had dizzy spells (and other related symptoms), many doctors blew
them off or treated the symptoms for decades. They got worse, the docs
still treated symptoms, and finally three things led to diagnosis and
the best "cure" available:
1. Severe drop attacks (Google 'em; they're like getting tackled by a
pro linebacker).
2. Sudden -- as in instantaneous -- total deafness in one ear.
3. My own differential diagnosis (matrix of my symptoms vs all potential
causes) helped teams of physicians begin eliminating many, and finally
all but one, of the potential causes.

My particular cause (Meniere's disease) isn't relevant, but maybe step 3
would help you narrow down your search. My docs said mine helped them
immensely. Example: as you know, hypotension commonly causes dizziness,
especially upon standing up.

I'd Google dizziness and its various synonyms -- with keywords such as
causes and symptoms, for example -- and start building that matrix.
Hurray for search engines!
