I had open heart surgery 6 weeks ago; I by now that I would be feeling relief from the pain and discomfort associated to the post-operative recovery. In the last weeks, I have been feeling a very deep and painful "burning sensation" on the skin around my chest area. This burning sensation worsens at night and it keeps me up for hours. During the day, it is a bit less painful, but it still does not allow me to rest.
Does anyone know what could cause this? Is this normal during recovery? Maybe an allergic reaction? Doctors have prescribed me various medications but nothing seems to be working.
