Foot Filter: I know y'all are not my doctor, etc, but I'm looking to the hive mind for some opinions. What are some possible causes of non-painful swelling on the top of one foot? (The usual looong story inside.)

Three days ago I happened to notice that my left foot was swollen on the top, between the part over the arch and just short of the base of the toes. It wasn't painful nor discolored nor warm to the touch. I wouldn't have even noticed it had I not had trouble scooching that foot into my slipper. It is only on the left foot, it doesn't affect the ankle, the toes, or any other part of the foot that I can see, and it doesn't affect my walking or range of motion. After the first time I discovered it, I noticed that when I woke up the next morning, that foot was back to normal. But then later in the day, the swelling had returned. (I work from home as a writer, a sedentary job.)
When I Google "swollen foot" I get all sorts of dire diagnoses like liver and/or kidney failure. I have an appointment coming up with my rheumatologist in three weeks, so if at all possible I'd like to wait and ask her what the heck is going on. (Actually, in a perfect world, I'd prefer that my foot stop doing this long before my appointment.)
Additional info that might apply: I have Lupus and circulation issues (Reynaud's syndrome, anti-phospholipid syndrome) and have always had very cold feet, but never any swelling. Even when traveling on overseas flights my feet never swelled. However, about a month ago I did slip and fall in the bathroom and took the brunt of it on the left knee. Within the hour, the knee had puffed up, so Mr. Adams took me to the ER. X-rays determined no breaks or serious damage, but I did get serious bruising after the fact that not only covered the kneecap but aslo extended down the front of my leg to just above the ankle. (I'm on a daily baby aspirin regime, so I've always presumed that's what causes my extreme bruising.) I'm wondering if this previous trauma could have anything to do with this foot swelling? Some sort of tiny blood clot or something?
Again, it's not painful or discolored in any way, so for the moment I don't think a visit to the ER is in order. (Unless the hive mind medicos tell me that this is in fact a sign of liver failure or blood clot or some other dire condition.) The swelling goes away after I nap (that is, when I have that foot parallel to the rest of my body.) Any ideas as to what the problem is?
