Sinus rinse after surgery, it's scaring me!

[Anonymousemouses]

I had FESS and polypectomy on Friday afternoon.
Yesterday I had to start using the NeilMed sinus rinse thing.
I held my finger on the kettle for two minutes, to ensure it was boiled for long enough. I had washed and microwaved the NeilMed bottle to sterilise it.
Today I boiled more water and put it in a clean water bottle to cool. I then tried to sterilise the NeilMed bottle in the microwave, but accidentally left it too long/left it wet on the outside and it melted. Luckily I had another.
I got worried about the boiled water being left out too long, so after doing the rinse, used the boiled water to clean the NeilMed bottle. I've left it to dry on kitchen towel, with kitchen towel covering it.
I put the water bottle, with the freshly boiled water (let it cool for 45mins - 1 hour), in the fridge to use tonight.
Now I'm panicking. I'm panicking whether the water would have more germs in for leaving it to cool before putting in the fridge, panicking about the NeilMed bottle being washed and not sterilised.
I worry that the pain is worse because I did something wrong and have given myself an infection. Most things online say to use distilled water, but the ones I see say they are for irons, etc. I don't think I would trust it more than boiled water.
Everywhere keeps on about this brain eating amoeba.

are you in the UK? If so there are no brain eating ameobas in our water
You sound very anxious about it - boiling a kettle for two mins?
follow the instructions and stop over analysing - it will be ok

Yes I am, my son told me about it and I think it's worrying me more as I'm in more pain today. Is it OK to use the water I boiled at lunchtime and put in the fridge?

The instructions say to boil for minutes or use distilled water, but the NHS said rolling boil for a minute is OK, it's the conflicting advice that's scaring me - I do suffer from anxiety a lot

Brain eating amoebas aren’t just spinning through the air waiting to try and get into your water as it sits on the side. They enter water supplies through environmental runoff, contaminated groundwater, or by colonizing biofilm in inadequately chlorinated pipes, water heaters, and water tanks. Your water has been boiled and then remained in its bottle away from any additional sources of moisture.

It is fine to use.

Yes
use the water

You can ask the GP if they can give you a bottle of sterile water if you're worried but you only need to boil water then then let it cool, the pain might be because the anesthetic and meds have worn off. Where is "everywhere" talking about brain eating amoeba? What about the thousands of people who get bath water, seawater, swimming pool water up their nose, how old is your son.

You can buy saline, if that would help?

I think the saline is mixed with bicarb and something else.

My son i 34.

There are tutorials online, I think the sachets already have saline and soda bicarbonate in them

I’ve used neilmed - I boil in saucepan for the requisite time - leave to cool with lid on. I use boiled water to wash it out and leave on kitchen paper to dry. Myself snd son (adult) have used it with no ill effects.

Thank you. I did the water I boiled at lunchtime and left in the fridge tonight and I think it was fine. I used the rest of the boiled water to rinse after washing.

Both nostrils were clear tonight, which is surprising as there is dissolvable packing and it was bleeding last night.

Thank you all for your help.

I do a nasal rinse quite often. It's very effective for hay fever and other allergies or sinusitis.
I just boil water, add salt and bicarb and use a neti pot which cost under £5 from Amazon.
I have to say DS2 who is a biologist was horrified but as others have said there's no risk in this country.
