Solar flares, coronal mass ejections and increased solar wind cause my joint pains to flare up. Increased geomagnetic activity causes me increased fatigued and a feeling of being quite literally 'spaced out'. I participated in the "cloudy with a chance of pain" research undertaken by the University of Manchester, UK during 2017. They were looking for a correlation between pain and earth weather but I expect if they can obtain data for space weather and run statistical analysis between that and reported symptoms it may prove what some of us are feeling. It really is crippling.
