It works amazing if your throat or sinuses are infected. I have taken 800mg of pills and barely take the edge off. 100-200mg of children’s liquid ibuprofen is complete relief and it tastes good. Once in a while I will get a bad sinus infection that ends up in the back of my throat and the pain is so bad I can’t swallow water. I got the trifecta once that included my ears and I had to get some drops from the doctor.
Yeah, I think I remember something like 10-20k to refill the cooling on an MRI, and that is just topping it off as some is slowly lost. The helium is just used to cool it. Helium is helium, so no such thing as medical vs not. The cost to repair this thing is going to be absurd. They are making better machines now have little to no loss, but I don’t think those are super prevalent yet.
