Yikes, since coffee is dehydrating and you should drink a glass of water for every one you have...so you have been in negative hydration recently. It's no wonder every joint didn't hurt.
And the cure for edema, counter-intuitive, is to drink more water! http://healthyliving.azcentral.com/...a-12289030.html This article also states to increase water slowly, but you have blown past that recommendation already just stay off the scale.

Tip from recent Arthritis Summit. Cartilage is 80% water, first thing to do for joint pain is drink more water. And my own tip gleaned from who knows which doctor, is drink 16 oz of water after awakening before drinking coffee, and a cup before meals. Your weight is the lowest in the morning as dehydrated, water then helps all systems return to normal, function well.
And if you are up for it, add a T or 2 of ACV to the cup of water before meals. http://forum.lowcarber.org/showthre...20&page=1&pp=15
Not suggesting you gulp down some crazy high amount of ounces based on your weight, but anybody needs more water than you have been drinking. Coffee, tea, alcohol or caffeine in anything does not count.
