Good morning Guitar
It was very hard to read about all your sister has had to endure through. I am so sorry! It must be unbearable. I can tell you are very concerned about her care and her healing. Who could blame you? By your own account, they are not specialized in burn care. It is very concerning.
I did not know much about burn wounds. I spent a little time learning about this morning this is some useful information I have found so far....
"..... a second-degree partial-thickness burn can progress to a third-degree burn over time even after initial treatment. Distinguishing between the superficial-thickness burn and the partial-thickness burn is important, as the former may heal spontaneously, whereas the latter often requires surgical excision...."
~~> Burn Depth
" Third-degree burn: A third-degree burn, also known as a full thickness burn, destroys all the epidermal and dermal skin layers. The tissue damage extends below hair follicles and sweat glands to subcutaneous (fat) tissue. With this degree of burn, the skin becomes charred and leathery and often appears depressed relative to surrounding tissue. The skin can be bright red, waxy white, tan or brown; there are no blisters; and third degree burns may cause massive swelling. Perhaps surprisingly, third degree burns are usually not painful because the injury has destroyed nerve endings. Skin grafting or other replacement options are required for treatment of a third degree burn.
When a burn injury is deep enough to involve muscle, bone, tendon and/or ligament, it is sometimes classified as a fourth degree burn. These burns are often life threatening and may require amputation."
