Its welcome relief, and from what little I know or experienced with it, you need a good doctor, or would it be specialist ? That seems to be the key, no parts replacers, you need a true mechanic on that job, or it may just drag on, and sometimes or in a situation like with my father it was life threatening. He kept having very close calls with asthma, and the doctors he was dealing with, never got to the root of the problem, he finally sorted through them, and suffered like h$ll the whole time, and got a real mechanic, not a parts replacer or should I say medication prescriber! This doctor made it his business to get to the bottom of this, and they concluded that sinus surgery was needed, there was an obscure infection that was just perpetuating itself, manifested so deep, and just triggering the asthma and copd like problems. Well after that surgery, he was about cured, though he caught some common illness and we almost lost him because it compounded the situation, but 18 months or so later, to the present, he's almost a miracle, can't tell you how the man suffered and was debilitated.
Everyone is different, just a story to share but, if he kept listening to the previous medical people it would have killed him.
I had a rupture in an artery in my nose, the cartilage section in the middle, and could not stop the bleeding, I was in Manhattan and the 10th precinct came to my office and whisked me off to St Vincents, siren going and all that, it was really weird, but my shirt was blood soaked as if I had a serious injury, I was in a conference room chair with my head tilted way back, darned phone ringing off the wall, Bill we need this, that, I had to hang up on them and explain later, was that bad. Those NYPD guys were a blessing, I am truly thankful for what they did. At St Vincent's they packed my nose like a cannon, I mean packed it tight, then sent me to a specialist, who took me right in, emergency, and cauterized it. I did a lot of follow up and this doctor was a real doctor who took all precautions and really focused on me, I had a CAT scan, revealing small passages in the sinuses and I told him I have problems with it since about the age of 30. He said the same thing, irrigation and or similar and in the dry winter, dry air in the house, there is relief, colds are tough because they pressurize so I am careful with hygiene and germs, eat right, keep the immune system up and try and get rest.
Good you found some relief, its a hard place to deal with and needs the best medical professionals you can find as far as I can tell. !!!
