My leg looks kind of "chubby" from the edema but I thought it looked better while I was taking the pic. As one can notice the 'ring' has gotten smaller. Again, I generally wash the ulcer with a washcloth with a squirt of Hibiclens while showering. The ulcer produces no pain so washing isn't an issue. After showering I let it dry real well and then apply some Neosporin on the edges after which I cover with a piece of soft paper towel. "Viva" brand paper towel is the best I've found so far, soft and absorbent.
Also a good tape is required. I've been forced to use all types of tape throughout the years. Its best to purchase online. The medical tape I see at my local drugstores is really expensive about $6 bucks a roll and its low quality clowntape. The 3M Micropore tape works great. I like the 2" or 3" widths. Even when I had my "leaky leg" problem the Micropore tape held up. The pic shows a 6 pack of Micropore I just got online for about $10 bucks delivered.
To save a few bucks I have no problem using Wal-Mart or Target house label versions of Neosporin. I'm not sure why its so expensive. I have a Target near me so i nave been using their 'up&up' triple antibiotic salve. Its at least 50% less costly than the Neosporin brand.
