Er, Well I had both. The good news.....the carpal tunnel went very quickly, the pain lifted after a few days, and the numbness within a few weeks. I had had it from about 20 weeks and was wearing splints most of the time. As for the SPD, I had it from about 10 weeks and was signed off work for the last three months of my pregnancy and on co codamol regularly for pain relief. I can't say it got any better straight away, now 6 months on I still have pain but it's nowhere near as bad as it used to be and really only when I exert myself. Fro some people it does go the day baby arrives though so it might do for you. My GP has said it's fairly normal for the hormones still to be affecting ligaments for up to a year after birth so I'm hoping it will be gone by then!
