Hi, <strongCustomer, Your son has multiple symptoms and he really needs a complete medical evaluation from head to toe to determine what is producing all these symptoms .
I think that in his case , it is extremely important ruling out the possibility of he having an autoimmune disease ( in this condition , the immune cells that in normal conditions only attack and combat viral or bacterial infections , begin to attack other body cells , including the gastrointestinal cells ( red blood in stools ,bloating ,abdominal cramping) nerve cells ( confusion ,difficult thinking,muscle twitching ) , or bone tissue (chondritis and hip pain) ).
There are multiple autoimmune disease like : Crohn's Disease ,ulcerative colitis ,lupus among other ones .
Your son should consult two specialists : a gastroenterologist and a rheumatologist specialist .
They will perform several tests including a colonoscopy , rheumatoid factor , C Reactive Protein , ANA antibodies , ERS rate , white blood cell count among other tests .
With these test results , the doctors will be able to determine or rule the presence of an autoimmune system disease to give him the appropriate treatment .
