Abdominal binder reduces my chronic headache intensity

I have been dealing with chronic headaches for 2 years. Every single day is a struggle. However I tried wearing an abdominal binder after researching stuff about different headache types and what can help. I suspected csf leak and tried the binder to see if it helps. And to my surprise it does. Now I don’t know it helps. Could be POTS, dysautonomia, leak or something else.

I wonder if anyone here has tried an abdominal binder for their headaches and noticed an improvement ?
