ps. Dr Matthias is great. He is learned of course but also listens. He is not in a rush when he speaks with you on the phone. Have questions ready for him and write down what he says after your call.
He will prob get you to do a lot of bloodwork but that is normal for all of us here heheh. Give Dr M my regards please and also his secretary Gwendoline. Love her accent.
best to you, THK.
