Sounds like you have alergies, what I use to do when it got real bad was buy a small can of jelpeno peppers, get a spoon and drink the juice carefully it would cause my nose to run, I would blow it to get out what ever was currently irritating it then start some antahistamine.
I have nonstop sinus issues, so that I'll usually get a cold that will later need antibiotics for treatment. Sudafed/Pseudoephedrine has really helped me. I believe in most states it is over the counter, but in Oregon you need a Rx or to drive out of state. I take Benedryl, Zyrtec, Flonase, Iodine nose rinse, Sudafed, and a Nettie Pot. I'm still congested, but at least I can blow air through my nose a little bit now.
I did years ago. It turned out I had a deviated septum that wasn't letting my sinuses drain, hence the infections and headaches. After surgery in 2007 I rarely ever get congested. When I do I try to eat spicy food or smell something that will make me sneeze. Once that happens it drains. In the meantime I microwave a most washcloth and last it across my eyes, nose, & forehead.
I actually purchased a personal stream vaporizer, made by Vick's today. I haven't used it but you put your face into a mask address where the stream comes up. CVS had it on clearance, $39.99 for $9.99...I couldn't pass it up at that price because my ENT told me to get one for my dry sjogrens symptoms in my nose & mouth.
I have a lot of sinus issues and seasonal allergies. Since I have a deviated septum, I'm at a disadvantage from the start. I do however use Simply Saline. You can get it at any pharmacy or grocery store. It flushes out the goop and also it's natural so there is no burning to the lining of your nose or sinuses and there is no bad taste or burning in your throat. I also use Benedryl when it gets really bad. I hope you feel better soon and find what works for you.
My 3 yo daughter seems to have it....it's so sad I can't give her anything for it. Doctors reckons it's due other eczenma.....I'm like wtf? No second opinion was given. The pharmists advised some clarantyne, that worked....least they were more helpful than the doctors. I love talking to my pharmists :)
Bless her heart Octobot. My granddaughter has to use claritin and if her asthma kicks in she uses a nebulizer with meds & vapor mist. Check at your pharmacy for the personal humidifier or vaporizer. It wouldn't be as hard as trying to flush her sinuses with saline.
You could also do it the old fashioned way... My grandmother use to heat water, pour it in a bowl, make us sit with our heads over the bowl, and then put a towel over us so we breathed the warm mist.. We thought it was fun because she made a game of it when we were your daughter's age, playing peekaboo. 🙏🌼
I have for 28 years. I had enlarged turbinates and a severely deviated septum. Had my surgery back in January and still didn't help the breathing. Started taking sudafed and its been the only thing that has helped me breathe and it takes away the pressure. I've been on plenty of antibiotics and none have helped. I take an allergy pill and the sudafed and it works for me (and I have a long history of chronic sinusitis)
