you can absolutely get physical problems from anxiety, and many weird and scary variations. I think chest pain is one of the most common.

Thats one of the hardest things i have to deal with, i have congenital problems that are rare and docs know little about, and a common problem with anxiety is believing there is something serious going on medically the doctors have missed. The balancing act is working out what is illness and what is cause by tension and stress. The hardest bit is stopping the behaviours that cause the anxiety related symptoms.
