Thank you for your response. I appreciate your thoughts. Yes, I was referred to a vascular surgeon. I was lucky to get an appointment for Monday after work. not sure what he will do during the consult. I just hope that the symptoms present themselves during the appointment. Today the first digit on my fingers looked almost black, then dark blue and then red., but not too cold. i am getting pretty concerned about the symptoms. Don't really want to take any more time off. What type of surgery did you have for TOS? Time will tell. Just want to get some answers.
