Hi, welcome to our site. I am Dr Saumya Mittal. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query My friend your symptoms sound like those of cervical radiculopathy. the pain would typically affect your arm and would radiate- as in seems to move from the shoulder region to the arm region. i hope there has been no history of trauma. i would suggest an x ray of the cervical spine- ap and lateral. and if possible, an mri of the cervical spine. i would also like to know exactly what has been wrong with your hand. you said its a congenital problem. we need to know this as some disorders go in groups. meanwhile you should meet a local dr to start you on pregabalin or gabapentin. they are both antiepileptic drugs that will help you get relief in pain. and a tab of amitryptiline is a better painkiller fir you, if this turns out to be a radiculopathy. you will also need to meet a physiotherapist for regular exercises, if this proves to be cervical radiculopathy in the xray/mri I hope this helps you. Inform the reports mentioned above so i can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided.

Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)
