Im very afraid right now. When I was on my way back from Colorado with my parents, my feet and lower calves were swollen, and they felt strange, but over time it got worse since we got back. My calves and lower knees are swollen, and my forearms, as well as my upper arms are begining to swell. My lower belly as began to swell up, as my behind is doing so as well. Please, this is most urgent. I need advice. Let me know if you need anymore info.
