Hello. I'm sorry you don't feel well. Your symptoms could be caused by a number of disorders, including autoimmune diseases (lupus, celiac disease, rheumatoid arthritis
, etc.), a chronic infection (HIV, hepatitis B or C, etc.), endocrine disease
), metabolic disorders (e.g., liver disease), fibromyalgia, or chronic fatigue syndrome
. Without a thorough evaluation -- which will include some blood tests and possibly referral to one or more specialists -- it isn't possible to diagnose your condition. I suggest you see your physician at your earliest opportunity.
I hope you have some answers soon!
