Gua Sha'd my pain spot for migraine relief

I get my headaches and migraines from one spot in my neck usually. I have done acupuncture and deep tissue massage and have not been able to get it to relax.

Last night I had enough and ended up using a bar of soap to gua sha the muscle. I'm sure I did not use any proper technique, however, the knot seems to be gone. It feels like there is a pocket now instead of the knot/lump and I cant tell you how much better it feels.

The area is sore today but still relaxed.

This was a desperation tactic but it seemed to be effective
