That's why I'm trying to get the opinion of experienced people. I have been following this topic very actively for years. I also had an HT performed by one of the doctors mentioned. (You can find out, what I think about the result in a previous post, if you want). now the question arises for me, do i go to the same doctor or do i look for a "better" one. this is very difficult and stressful for me right now. so I ask for your understanding. melvin i also follow you very actively and find your work very helpful. since you are a moderator and proceed in a balanced manner, you are welcome to send me your opinion privately. I would be very happy and thank you.
