I have been told my migraines are TOS related. Observing hand use limits and regular walks help me alot.

Standard migrane meds help. You can take a daily preventive drug if your headaches are quite common ( ad ozen a month) Topomax and verapermil are the most common preventitves.

Injections into the base of the skull can help some people as can biofeedback,feldenkrais, relaxation exercise.
