Can migraines cause back stiffness, balance trouble, vision trouble an sweats ?

Sure: but double vision, and your other symptoms are very worrisome and require medical attention and probably brain mri

Migraine symptoms: usually do not include back pain or sweats. Unsteadiness ( if limited to the headache) may occur. The same goes for visual disturbances. I recommend a consult with a neurologist (there is one near the LIBERTY TREE MALL and a few in Beverly and Andover as I recall) Let us know if you have further questions.
