It still looks like mostly udder edema to me. The holsteins that I have seen over the years will have it for anywhere from 2-3 days to 2-3 weeks after calving. Sometimes the farmer will give them a shot for it, but it often will hamper the milk production. So if it stays the same or slowly goes away, leave it alone. Her body will re-absorb the fluid in its' own time. If it gets bigger then I would say possible hernia. Give it at least a week or two if it is not hot or red or looks like it is causing her any real pain. The tighter/harder the udder usually means more edema to be worked out. Use one of the products for dairy animals that has the mint in it, to rub on it. The formulas cause a little heat but mostly increase the blood circulation which will help the fluid to be absorbed into the blood stream and carried out of the area. Those "creams" are more liquid than say bag balm, smell like a mint field and do a fantastic job of increasing the blood flow.
