I have dry eyes, dry mouth, rinitis, metal smell when i breathe and raynaud. are there syntoms of another disease?

Possibly: The dry eye and mouth may be symptoms of either primary or secondary sjogren's syndrome. Raynauds can also be seen in sjogren's or other connective tissue disorders. If possible, see a rheumatologist.

Autoimmune disease: Your description sounds like an autoimmune disease such as sjögren's syndrome, lupus, or some other disease. See a rheumatogist.
