Chronic fatigue could be due to several causes like anemia, multiple sclerosis, depression and other psychiatric disorders, hypothyroidism, infectious mononucleosis, post viral all can lead to chronic fatigue syndrome. Nausea could be due to gastritis,hepatitis,gall bladder problems etc.There will be pain in the right upper abdomen along with nausea in gall bladder problems. If you are still doubtful that it is due to gall bladder problems discuss it with your doctor. You may need an ultrasound. I hope it helps.
Best wishes and regards!
Thanks for the comment. My next appointment is scheduled for April. I will inquire about a gall bladder ultrasound. I don't anticipate an objection to this. If nothing else, it might rule out a gall bladder problem.
