hmm MP did you happen to also begin drinking different water or something at the same time? Someone else cook for you? It sounds more like a real increase in sodium/salt, imo. But if you really taxed your joints, yes, they can swell... it's from the body trying to heal the "injured" areas.. common in arthritis... ice and elevation, plenty of water too helps (no kidding) Can you take some ibuprofen? I think you need your spouse to wait hand and foot on you too
