I get that when I get a hot flash. washing your hands and feet with cold water helps a little. Sleep helped me and not standing up too much.
Im taking my fluid pills so idk What's wrong
That's how I was my first pregnancy. When I walked o felt like my skin was about to rip. And I had my adjustable Velcro sandals stretched the whole way to wear it barely connected. I would prop up my feet for a couple hours above my heart and walk around for 5 minutes and they would go back to how they were. My doctor told me to just prop them and cut down on salt.
You should talk to your Dr about it hun. No soda or salt either. Laying on your left side really does help, so does a cool bath/shower. I hope you feel better soon!
