Yeah, i can understand that. Hopefully the specialist can help him and explain it all. Dealing with physical ailments is hard especially if others cannot see them. You can be in screaming agony but it doesnt show, so people expect you to be 'normal' when you're not. I have some of those.. i tried pretending or just dealing with them. It was fine until i was forced to change hours at work and was taking the bus during rush hours both ways. Things got bad and very painful from all the standing. Until in late 2018 i had to start using my cane full time. I'm 35 years old and people don't believe you need help ... sorry, but i do. I hope your ex gets some help.
