48 hours ago my left thumb and index finger tips went numb after a firm front neck massage. the feeling has still not returned. should i see a doctor?

Yes: This suggests that you might have something (like an intervertebral disc)pressing on a nerve in your neck. It could be related to the massage if it was forceful enough to put your neck vertebrae out of alignment. You can see an orthopedist but I advise seeing an osteopath who does osteopathic manipulation- see http://physician.academyofosteopathy.org/ (or a direct non-force technique chiropractor)
