Aww Danni, that's no good.

I've never liked putting anything on my skin when pregnant, that's a personal thing though. I'm not sure on those things safety wise.

But I can tell you my lifesaver - a heat pack. I buy those $20 ones with wheat in them from the chemist, you just pop them in the microwave. They are great! They are shaped to fit around your neck, and really help my migraines which have gotten bad since I stopped metformin on Monday, and also aching legs and neck.

A call to a pharmasist is always informative too, sometimes I think they know more about safety of things like that than doctors.
