are you based in KL/Selangor?

Chiropractic adjustment helps with my friend's headache. For me it gives me good night sleep after I had the neck adjustment. It certainly helps with my back pain but I also do some yoga exercises a few times in a week to ease the pain. That helps too.

In Malaysia, adjustment is expensive. The cheapest I found is in Bukit Jalil that is RM75 per adjustment.

And yes like the others have said, you will need to visit a few times to see the effect. It also depends how severe your condition is.

My friend had cupping done for her migraine and helped her. You might want to try that too.
