S.S.
You did not state if it's in your hand or foot...However, since you do repetataive work it seems it would be highly normal. If it's in the hand, try wearing a brace similar to one worn for Carpal Tunnel Syndrome while not at work. If in the foot, elevate as much as possible and wear good supportive flat shoes. Since you are pregnant, there isn't a lot of meds to take and extra strength tylenol is ok. Talk to your Ob/Gyn for further advice and he/she may refer you to an Orthopaedic. I've worked in Ob/Gyn for 23 years and this is usually what we recommend. Good Luck!
