Apparently they sent the doctor an email, which I did long ago myself with no response. The guy said he will call him today. It's such a mess. Time is passing and no progress towards my surgery is being made while I get humiliated and suffer pain daily.
It took months to get my mother, as a german citizen, surgery with chronic pain and I, as a german citizen, still don't have the therapist I need. The only ways to get an appointment quicker are moving somewhere where someone has time or an emergency, to which chronic pain does not count. (Or getting lucky, I guess)
