My legs/feet are always swollen too, and your post brought back a memory - our cat was under my bed, and my husband was vacuuming our bedroom, and he tried to get under the edge of the bed, and scared the cat. She came barrelling out from under the bed and used my legs to pounce off of with full claws out, and put several puncture wounds in my both legs.
For the next 4 days I had water oozing out of the wounds continuously. I soaked through every kind of bandage I put on it, but the worst of it was, I didn't know that could happen, so, I was terrified that the cat gave me some kind of infection or something. Finally, on the 4th day, my husband called our local E.R. and spoke to a nurse on the phone and she asked if I normally had edema in my legs, and then explained that it was just water.
The one good thing was that for a few days, my legs almost went down to normal size!
Tony: I am a diabetic as well and my feet are very dry and I have had a couple of cracks that are very painful - I have tried every lotion on the market (no exageration) and I have found that Avon Moisture Therapy Intensive is really good and a close second is Gold Bond Ultimate Healing (I hope it is ok to list these brand names, if not, I'm sorry).
