Suffers From Sleep Apnea, High BP. Knuckle To Fingertip Are Blue And Numb Due To Driving. Should He Rush To Emergency ?
Thanks for posting your query.
The blue color of his fingers and palms with numbness is suggestive of a compromised blood circulation in the area - It could happen due to an exposure to cold, vessels and nerve compression due to abnormal posture while driving, Raynaud's syndrome or a blood clot.
You can ask your friend to warm himself. If after warming the fingers or after mild exercise of hand the color returns to normal then there is nothing to be worried about and he can go for a routine check up after he comes back home.
In case the blue color is persistent, then he needs to attend an emergency room to rule out any blood clots.
I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wish you good health.
Regards.
