I can't help with the SPD, but the carpal tunnel will get better soon after bub is here. It is a horrible condition but i think by a month after bub was born i didn't have any symptoms. It eased earlier than this but took awhile to completely go.

I had pain from seperated stomach muscles and carpal tunnel and hated it because the pain seemed senseless. What was the point of it- the bub wasn't in my wrists. But the pain of labour was completely different- because there is a point to it, you see progression and you know that it is helping to get your baby earthside and you know it will end.

take care
