Joint pain, hair and weight loss, fatigue symptoms but all negative blood work. rheumatologist suggests a shrink. any other suggestions?

Endocrinology: Another opinion from a different specilist such as an endocrinologist might be in order. Some of their diseases can cause simillar symptoms. I also might get one further opinion from a different rheumatologist or internist.

Maybe: It depends on what blood work was normal. Were thyroid functions tested or was it only rheumatoid serology tested? It may be anxiety or depression but it may be a medical condition as well. Make sure you see your internist as well for a full work up.
