As far as home remedies for carpal tunnel syndrome, the first and foremost thing I would suggest would be activity modification. Generally, if you can avoid excessive wrist flexion and wrist extension, that alone can solve the problem - at least temporarily. A couple times in my life I've slept awkwardly and I've woken up and my fingers have been numb. I think it's pretty common. I think it happens to probably just about everyone once in awhile and that's the point. The point is that if you can avoid the excessive flexion or extension of the wrist, that alone can be very helpful. Another option would be just to stop by the pharmacy and pick up a splint, which will keep your wrist in neutral position and in so doing that can help with the symptoms. Those would be some things you can try before coming in to see a hand specialist.
