Your current situation is plasma bubbles, but the fresh epithelium of your burn wound is tender after healing, and it is easy to separate from the dermis, especially when your hand hangs down, which is easy to cause purple wounds, needle-like pain and blisters. The treatment method is to puncture the blister with a sterile needle, release the blister liquid, keep the blister skin, and apply Baiduobang ointment externally.
