I tried supplementing with various forms of omega-3. It took me a while to figure out the exact correlation, but as it turned out, too much EFA in general made my skin bruise and swell up readily. Hence, the days where I took fish oil and ate almonds and a salad with oily dressing would leave me literally crawling to do things by bedtime because my feet had become so unbelievably swollen.

I dropped the supplements pretty quickly, but was now hyperfocused on the swelling, because it still cropped up occasionally, and, I now realized, had done so for years, but in the past I had just written it off. It took another six months to figure out that vegetable oils - regardless of their ratio of EFA content - were the source of the swelling. Once I got rid of those, problem solved.
