That sounds very likely to be the mechanism. A few comments:
1) I remember when I was very young, complaining to my mother about my legs, she told me that the entire family experiences leg pain before and during an incoming change in weather that is cold, damp, or includes thunder/lightning. This coincides with my previous statements that it strongly appears to me that a large portion of my family and extended family are proto-mystics. That's to say nothing of the naturally occuring mystical experiences they rarely share even with each other.
I do not see how being electromagnetically sensitive is something that is only common to mystics. After all, I qualify as a mystic, but the only health response I have ever noticed with respect to storms is I tend to have more respiratory and sinus allergies a day or 2 prior to a storm. But, it is known that a cloud of pollen and dust tends to precede storm events. On the other hand, my blood sugar has risen in the last 4 days, so perhaps it is a response to an electromagnetic influence from the storm. I guess I will have to document weather along with my solar and geomagnetic and solar wind observations to see where the influence lies.
2) Lately, I've found myself observing the effects of simply resting my digital devices on my torso. This is going to sound crazy, which is why i've not shared it. But, every time I do, I experience discomfort in that localized region. It feels like things are being crunched, inflamed, and begin to feel like a strange, subtle burning. It's like the cells of that region are eating themselves. That's the most often way I explain it.
I've just recalled that digital devices emit electromagnetic radiation--although it appears to be "non-ionizing" radiation. It's worth mentioning research into cell phones causing cancer. None of this am I sufficiently informed about. But, i can certainly report my experiences.
Additional Note: I know nothing of HAARP other than the name, and it has something to do with the ionosphere and manipulation. But it's come to mind as I wrote this.
As crazy as it might sound to the herd, you might just be electromagnetically sensitive. The HAARP project functions on low frequency EMF, and it has been proven that frequency EMF can cause health problems for some people; however, I do not believe that the HAARP project is undermining the health of everyone on planet Earth, after all the earth has a low frequency EMF; however, some people who live near the HAARP antennae might be at risk.
Jan 31, My morning blood sugar reading was 168. My blood sugar is up 8 points from yesterday. Joint pain continues to be low and seems to be about the same as the last few days, even with a 2-day atmospheric storm still going on right now. I have never seem to notice that atmospheric storms cause me discomfort other than allergies.

I am beginning to see that just because there was a solar event does not mean that the earth is going to receive a significant solar wind impact. So, tracking solar wind is likely to be more fruitful.
