finger and toe joints hurting

I am almost on my 31st week. I noticed that my finger and toe joints started to hurt. I have been drinking milk and taking the necessary vitamins, such as b complex, but I am unsure why I am feeling this. It has been uncomfortable. I told my doctor about it but she just made sure that I drink my daily milk and vitamins. Has anyone encountered this during their pregnancy? Did you have any remedies whatsoever? Thanks.
