The doctors could not find a reason, but said that most likely it was brought on my stress.
My husband's been through a lot of health problems, and "brought on by stress" is doctor-speak for "WE HAVE NO FREAKIN IDEA WHAT CAUSED THIS" Over the years, i have heard SO many people go to a doctor for various symtpoms, and if they can't find anything in their med school flow chart, they brililantly pronounce it to be ..... .STRESS!
