Thank you for your question.Numbness
of the hands and recent engorgement of the neck and face and numbness may be indicative of something compressive around thoracic outlet. This is the area where the nerves to arms are coming out. Blood from neck and face drains into a large vessel called Superior vena cava
which is also in the same area. I would advise seeing a vascular surgeon to rule this out. CT scan
of the chest may be helpful if compression is suspected.
Wish you the best.
