You might have a pinched nerve in your upper back. I had the same thing a few years ago, same fingers. If you are comfortable seeing a chiropractor, I highly recommend it. Otherwise an osteopath or remedial massage should help. Of course just let them know your pregnant. Hope this helps
Thanks long_road. Looks like it's nothing related to the pregnancy then, although this started around the same time (so I thought it was related).
Youre not alone, I have had the same exact feeling... Coupled with random ear aches and flushing of my face. I try to not worry about it since im only 4 weeks and probably just overanalyzing. If it persists I would call someone.
