I had this later on during my pregnancy with Tehya. You might find it's carpal tunnel syndrome. I had a gf who got it pretty bad and quite early on in her twin pg, so maybe it's something that can be more common for multiples?? Basically she ended up having to wear wrist supports pretty much day and night.

Some of the other girls might have some ideas for you. Mine was only quite mild and as I was nearer to the end I just perservered.

Hope you find a solution hun
