I sprung a "leak" the other day on that area of my right shin where the tissue is thinnest and a venous stasis wound seems to just be on the edge all the time .. Weeping epsiodes from that spot though are MUCH less frequent or copious than they were before my surgery/weight loss, and was in fact a major inspiration for my WLS.
Butttt .. stupid me .. I got to picking at the area with my thumbnail the other night and <
sproing! > (I remember Dr. Antelmo grabbing my hands one day while I was talking to him, right after my surgery, and he whipped our his nail clippers and went clip clip clip right there, knowing that I was using them to pick at that area - lol) ..
When an edema spot is leaking, the only thing effective that I've found (and I hate to have to admit/use this) is a "light-days" women's pad, held in place with a velcro bandage wrap (I use the Ace ankle ones from Wal-Mart) ..

I sometimes sneak into the women's restroom at night in our office building to get one out of the dispenser machine, if the need arises at the time. If the leak is really copious, use a small Pampers instead (tear off the plastic edging part, fold in half/double).
Keep a close watch that you don't have or aren't developing cellulitis or another type of infection in that area while the weeping is occuring. You also want to change the pad when it's saturated, and dispose of that smelly thing in a place where the bacteria in it (which lymph is copious with)won't contaminate anything else. At some point the skin has to be kept dry in order for the "weep hole" (geez, sounds like we talking auto waterpumps

) to heal up and quit leaking. It can't do that as long as the skin stays wet with lymph. That's another reason for using the pads/diapers, since they draw the fluid away from the area, collect and hold it in, and not let the wetness touch the skin (think of how those diapers work to avoid diaper rash). Fortunately, after a few hours (or days, in my pre-op world) the hole will close up, the leak will usually stop and you can go about your normal biz.
