I'm 23w pregnant and i've had carpal tunnel surgery on my right hand before i now feel like it's back is that possible.

Normal: There is a lot of fluid changes in your body due to the pregnancy which can accumulate pressure in the carpel tunnel and mimic your former symptoms. The night splints, the vitamins for pregnancy, and some reasonable restrictions for repetitive hand use on the computer may be appropriate. A physiatrist (physical medicine) can help your gynecologist with testing and recommendations.

The fluid in your body: Can change and fluctuate with pregnancy and the fluid in your carpal connell and change as well so there may have been a time when the carpal tall felt better now there's been a shift or change and it's affecting things more a wristlet at nighttime often helps and there are many times when a single injection in the carpal canal can be offered as long as your ob/gyn agrees.

Yes: Pregnancy can cause hand swelling and irritate the median nerve as it passes through the carpal tunnel in the hand. Wearing wrist splints at night that keeps the hands in a neutral position can help. It should resolve after your delivery. Best of luck.
