Though I have not had your condition, I have had a mastectomy from breast cancer. However, after reading about your problems, you might want to consider a good plastic surgeon, one that has experience in rebuilding damages caused from radiation treatments. Radiation also can cause skin problems from breast cancer and after researching my options, I chose a plastic surgeon who had lots of experience with cancer. Though you only hear about the ones who can reconstruct a breast, they are skilled in a lot of areas the public never hears about. Since your eye doesn't close well and your smile is affected, he may can reconstruct that area of your face and at the same time possibly remove the built up scar tissue. If you need a dermatologist for the itchiness, I would want to choose one that could work with the plastic surgeon. It would be worth a consultation to see if there is any help they could provide. Good luck!
