Heat doesn't help swelling. So Idk why a hot bath would help. Try ice. The cold gets your blood circulating better. My blood pressure is always perfect but I still swell a lot.
I don't know if drinking water will help since I have never been in your situation but if I were you I would let your Dr. know in the morning unless it gets worse then I'd call tonight because they may want to check your blood pressure.
Yeah, and soaking in Epson salt...even taking Tylenol..Havnt been drinking that much water cus I need to refill 5 gal jug the sink water tastes weird
You may want to contact your Dr because swelling is a sign of preeclampsia. Have you tried elevating your feet?
