It looks like we are getting closer to answers. They think instead of this being a true infection it is more an autoinflammatory response. They are thinking Sweet Syndrome or Pyoderma gangrenosum but leaning toward PG. Both are very common in people with blood cancer. Simple explanation, the white cells attack for no reason and painful blisters form as a reaction to the attack. They are going to start steroids today and watch over the weekend. If they are correct and it is either of these there will be improvement. If it is Sweet he will heal in a few days. If PG it will be months. Once they know which one and get the meds figured out we can come home and he can work on getting better there. Steroids decrease the immune system but it’s also the quickest and best way to treat him right now. Please continue to pray for him!
