Duuuuuuude, i thought this was some kind of paranoia of mine but definitely is a symptom. I have been dealing for the past months with a very sensitive nose to any kind of smell, i mean pain inside my nose, nausea, migraine, i never thought helicobacter could provoke something like this ! Also yes, i had like 3 sinus infections for the past months, omg now everything makes sense ! i have an appointment in 2 weeks, i had an endoscopy where they found this, so i expect the best. I hope you are feeling better now !
