This is interesting! I've been having some pretty bad intermittent panic attacks over the past year or so and a thing I've noticed is that I have general inflammation across my body along with the panic attacks. For a long while I thought it was an infected tooth, but with that fixed and the panic attacks still ongoing, I'm not sure! But this is a nice confirmation that there's some correlation.
outside of the panic attacks, do you have periods of pleasurable excitement, fun-loving life of the party, or superproductive creative inspiration? consider "bipolar ii", and low dosage lithium can work wonders on both ends of the emotional spectrum. ianad and not diagnosing, just mentioning that lithium is a mineral salt found naturally in the freshwater in parts of the world, and in those places people have more stable moods.
