Symptom Addition

I wish the symptoms thing had an option for "swelling/body cramps" or something. I know its a less common one, but on top on back pain I always feel really painful and swollen around my butt, legs, and sometimes even my feet for the first few days of my period. But I feel like "back pain" isn't a good descriptor for it. Maybe just "lower body pain" or "swelling"? Any other input?
