Do you have copies of your medical records in Papau? It sounds like you need to see an endocranologist and a complete physical. Be sure the Dr knows about your lack of O2 when talking or singing. That’s my suggestion. Have the Dr check your diaphram.
An endocrinologist? What is that specialty?
I don’t have the records from Papua. It was at Rumah Sakit Dian Harapan (Hospital Hope Lamp - it is a catholic hospital).
I have told the docs about the stopping of breath. Generally, I start there. The earlier US docs, well, also the Papuan docs, did check the diaphram. They said it was good.
