Perhaps some of the bacteria from that painful pustule in your left nostril,
which you zapped, was able to spread into your nasal areas and turbinates?

After I suffered with multiple sinus infections, year after year, for
decades, I experimented with flooding my nasal passages with a mixture of
diluted 3% hydrogen peroxide, baking soda and kosher salt. In order to flood
my nasal passages and keep them flooded, I keep my forehead pointed
downward. I keep my forehead down for quite a while, hoping that the
anti-infective mixture can get to the infected area(s) within my sinuses and
nasal passages.
.
It works! I have been sinus infection free for about 3 years. I think that I
had chronic infection problems with my turbinates, so flooding my nasal
passages with the anti-infective mixture worked very well, for me, since the
infected areas were fairly easy to reach.
.
I have fully documented my experience and how I did it at Healthboards.com.
There are posts there by people who have tried my "upside down sinus
flooding" and have received either partial relief or total relief. There are
also posts there from those who it hasn't helped, and by those who don't
think that it is a good idea. I have no connection at all with Healthboards.
I use it because I consider it to be the best facility for discussing health
problems on the Internet.

Hello TM... I would carry on with the irrigation. ...And don't blow the
nose!!  Just exhale lightly. ...Let the nose clear itself. Use the
irrigation fluid to help flush the bad away.
  ...I also had some luck clearing my plugged sinuses by lying face
down on a frozen (pre-dampened) face cloth. This caused a bit of
snapping and cracking within; however, after 15 min., I flushed the
entire infective material out.    Good luck to you.... Jon

Find a good ENT, one that isn't too inclined to recommend surgery quickly.

Well, you obviously need to see a doctor who can diagnose you properly.

But if it is a bacterial sinus infection that is secondary to your
catching cold, then it's entirely possible that it's resistant to the
amoxicillin.  There are other antibiotics to try in that case.

What happens is that the viral cold causes the sinus cavities to swell
shut.  Then bacteria can multiply inside the now-closed sinus cavity.

Sinus infections tend to be stubborn.  Even after you find the right
antibiotic, it can take 3 weeks' worth of antibiotic to completely knock
out the infection.

If all that fails, the next step is to see an otolaryngoloist
(Ear-Nose-Throat/ENT) specialist.

In the meantime, frequent nasal irrigation can give a lot of relief.
Sometimes, if you're lucky, frequent nasal irrigation can even knock out
the infection.

If you search the Google archive, you will find the various FAQs for
this NG--the original one plus the one I authored.  They'll explain all
this in more detail.

Good luck.

Hello, Mullen,
Strange the medication didnot work; stranger yet is you didnot call
back your Doc to tell him it didnot work. Before you screw up big-time,
call your Doc. immediately and tell him what is happening, so he can
immediately change your prescription. Tell him about the pimple, as
it sounds as if you may have a Staph. infection, and i donot know if
amoxocillin works on Staph. Iwill look it up and let you know. Next
time donot wait the entire prescription if youare actually getting
worse on the medication, to call the Doc. and tell him!!!!!!!  Youhave
a bad infection, so donot listen to every jerk you come across on the
Internet. CALL YOUR DOCTOR NOW!!!!!! PLEASE!!!!!!!

Staphylococci (an important group of bacteria) have developed an enzyme
to break the Penicillin molecule apart and are thus rarely susceptible
to Penicillin.

Amoxicillin represents a synthetic improvement upon the original
Penicillin molecule.  Amoxicillin is better able to resist damage from
stomach acid so less of an oral dose is wasted. While it is still
susceptible to destruction by Staphylococcal enzymes, it does have a
much broader spectrum against the Gram negative cell wall and is able
to last a bit longer

In other words "Amoxicillin" isnot a good antibiotic for a Staph.

Methicillin is used for Staph. only

This is a good read for you.

Cephalexin has done a lot for my sinus problems, and i bet you it will
work for you too, not that you actually have a "sinus problem", but
will if you donot get rid of that infection immediately.
