Hi @erikas Thanks for you answer and for the contacts, I will have a look there...

My ENT prescribed me two different vasodilators treatments one month Each without success. He told me now that there was nothing he was aware of that would help for sure and that if I was willing trying more medicines with no assurance it will actually help, I should contact him again. For the moment I am not taking anything but aspirins. This is why I am interested to know the experiences and evolution of symptoms of people suffering similar conditions since longer time.
