To my dim recollection throat is a important energy center. Emotions precipitate in this area, such as a feeling may be described as "choking one up"..a intense emotional feeling.
Personally I think regret or repressed emotion may incite a throat problem. It is repressed this is where it channel wise is kept. But I'd guess it could be any repressed emotion. So working with repressed emotion by meditiational means then may pose a bit of a solution...not short term but longer term to prevent such things from occuring. A energy obstruction of sorts this is where it stops in the throat. It is repressed to there.
Infection in mouth....toothpaste or mouthwash with tea tree oil may help. Washing ones hands with a tea tree oil soap may also help to prevent expousure.
Of course check with your doc....these are just personal obserations and suggestions, and I am just a simple bobo, on the internet.
On flu shots....one should of course not get them when sick in any manner. What I find with flu shots however is that they seem to exercise my immune system a bit. Immediately after for several months I will not catch anything. So I have taken them regularly for several years. I don't know of any medical opinion to support my thinking of this however.
Ill effects to my opinion usually that is the rare instance when one gets the flu just after the shot. Nasal flu immunizations....I would not do them.
I don't get sick much but would prefer not at all
. It is a good means to use this thing of sickness....but still I avoid it. I think I am not alone in that aversion.
I tried seeking out peoples sick, and giving them things for their colds...but alas that did not work
I have spread to many colds in my past by not washing may hands and such to prevent that karmic effect I think.
Next lifetime I will have to remember to be more careful.
A meditative remedy for regret or repression....all are differnet and with differing traditions and skills.
A remedy I may try.....would be to incite the idea I am OK, anything I may have done is the best I may have done considering the imperfect situation I find myself in.
I would incite that thought, and without modification keep it present in my mindstream that thing. I may do it that way at some time.
Presently I would incite the idea or feeling I am not present, but am witness only to myself sitting in meditation, all caused to include my heartbeat and breath by other, other being circumstance one finds oneself in...I find that a universal remedy of sorts to the idea of regret or repression.
And inciting and staying there seems easy, it seems to become the body that incitement. And it seems to carryover to not sitting.
Breathing I feel breathed that type of thing, each sensation, each movement of body or mind,thought..... can be observed in that fashion.
Hard to say that though...all are so different.
Anyway...I hope you feel better. At the very least....(if tibetan) envision you are taking the illnesses of others voluntarily upon yourself for others benefit....that can be very handy to develope the habit of compassion....so even this be used for good purpose. (easy for me to say I am not presently sick
Nevertheless it is handy to use it in that fashion. It may then serve great purpose...that providing of purpose may be in fact the actual remedy to that things occurance.....you become sick for then compassionate purpose..to learn compassion. So self may be less inclined to produce that thing.....as compassion works generally against self concept. So that may perhaps work for personal benefit as well.
So perhaps I would try that first. Taking on others sickness in meditation. It is easy to visualize oneself doing that. Do it and stay with it a little while.
Part of a meditation until one gets better. Check with your teacher if these things are OK first.
"This order considers that progress can be achieved more rapidly during a single month of self-transformation through terrifying conditions in rough terrain and in "the abode of harmful forces" than through meditating for a period of three years in towns and monasteries"....Takpo Tashi Namgyal.
