Oh Kelly (((hugs))). Please let your son know that you'll never give up until you find some answers for him. I too know that type of pain and feel for him. about 3 years ago I went through horrible right sided abdominal pain and alternating diarrhea and constipation and the doctors were sure it was crohn's disease. Long story short, all tests came back normal so the diagnosis for now is IBS and it's all in my head. Sad thing though is that my 15 year old son also has my same symptoms and severe pain at times. I am definitely not saying your son has crohn's and I am not a dr. but I know crohn's can be extremely hard to diagnose and can mimic appendicitis and cause skin and eye problems.
With the inflammation something is definitely going on. Maybe look into the camera pill. This takes an inside look at his small intestine. Has he had a small bowel follow through?
I hope you find some answers real quick Kelly. Give your son a hug from us. Let us know how it goes and NEVER give up.
If they are talking about an Addisonian crisis, they must think he has Addison's disease. Looking back on what you posted, it wouldn't be surprising that they came to that conclusion...a friend of mine's boyfriend has Addison's disease. I did a bit of research on it because I'd never heard of it.
Basically, the disease causes adrenal insufficiency - the adrenal glands (above the kidneys) normally produce the hormones cortisol and aldosterone. In Addison's patients, these hormones don't get produced. In 70% of Addison's patients, this adrenal insufficiency is due to an autoimmune problem - the patient's own immune system begins attacking the adrenal glands.
