When hubby is sick

. . . it feels like I am sick myself. It is really very stressful to me. I hate to see him suffer like this. He is never sick so this makes it all that much worse for us all.
It started a few years ago but with medication, it was pushed right to the back of our minds. Then for the last two (maybe three) months hubby has been suffering with a pain on this chest (no not his heart – we have had all tests known to man, done. . . and again . . . and again).
Yesterday it got so bad, that he ended up in the emergency room. The doctor on duty (what a nice man!) did a bunch of tests again but couldn’t find anything. He gave hubby an injection that just about knocked him out and took away all pain till this morning. :) Then today we had to go back so that another doctor could see if he could find anything.
Hubby is so despondent already as it has been months now and this was the fifth doctor he has seen. Doctor number 5 claims that hubby has Irritable Bowel Syndrome. I am searching the Internet as this means a whole new lifestyle when it comes to diet. There is so much he cannot eat anymore. But I am willing to give anything a try if it only helps.
