My father is suffering from a medical condition where his lungs have shrunk and become weak due to a fungal infection and he has lost lot of health and is largely on bed these days. He also loses breath when speaking due to this infection. Due to this condition, he has developed a wrinkled skin and a bed sore in the hip area. Although the sore appers to be healing from exterior after usage of T-bact however father complains that the pain has increased over last week or so. Please advise if we should apply T-bact or consult a doctor - if so, what doctor ?
