Since you are pregnant, you could have issues that normally wouldn't occur. I'd ask my Ob for an opinion.
That said, I've been going through an ankle recovery over the last 3 months with ortho and have been in the boot about a year. I wear a day brace and a night brace now.
Part of my therapy after stretching, etc is to use my hot foot bath for 20 minutes them follow with ice 20 minutes. I still do this daily.
Of course, before you do anything mentioned on this thread, run it by your dr.
I cannot use anything that is anti-inflammatory. My repair had to do with an injection and stem cells so I have to be very careful.
Best wishes!! Let us know what you find out.
