Hi Again Gurneet,
I recalled your post asking about vascular surgery. I did respond with some information for you. Address below.

So please help me understand better what you are asking.You may have some repeat testing, possibly some painless Doppler imaging of the vessels that feed your hand.
A vascular surgeon should be able to determine if you require a surgical intervention to treat your hand pain. But of course they will need to find a reason for the pain.
I assume you have had all the vitamin deficiency blood levels done? If not that may also be another possibility to consider.
I hope this helps. Again if you have a more specific question and I have not answered it please let me know.
Best of lcuk to You,
