Moose,
A few things here...
Have your doctor run a CBC and culture the site to see how your White count is doing and also what strand might be causing the problem at the wound, you might have an infection going on there (Bacterial at that) that might be in need of treatment by something systemic like Vanco or Cipro. If the culture comes back positive, along with your White count (Neutrophils) being high, then most likely you have a bacterial infection that, like I said before, will need a broad spectrum antibiotic, followed by maybe a topical antibiotic cream. The odds of it being viral are pretty slim, especially with wounds at the superficial layer of skin, but if the white count comes back high(Lymphocyte) then it probably is viral, I doubt it though.
If that option helps the wound reduce in inflammation, then the next step will be to just have your doctor stitch or staple the wound together. The wound itself doesn't look to be too deep, so healing by secondary intention (Allowing it to stay open and the granulation tissue to form) can still be an option.
If they have tried such measures but to no avail, let me know and I will give you some other suggestions..
