My dad suffered from TNP for a long time because he said the doctors tried medications and none worked. He instead suffered from the severe pain and lost weight and looked horrible! It took intervention from my family to get him to go back to the doctor. He then had a nerve block done and became pain free. The side effect is that he had permanent numbness on the side of his face. But it was worth it to see the life come back to him and gain his weight back.
