In you arms I would say it might be Carpel Tunnel or inflammation of the nerves ( I think they are similar anyways)

I did develop numbness in the feet and knees and my spine hurt for ages after my 2nd c/s. It was more noticable after my 3rd. I did a little research and it might have been nerve damage from the spinals.. I guess if you had the pain before then had a spinal it might have the same effect kwim?

Just type your symptoms into google (don't freak yourself out over the scary stuff though) but you might find some useful information
