My Daughter In Law Had A Baby One Month Ago.

My daughter in law had a baby one month ago. She had preeclampsia and they had to take the baby. Since the birth she continues to have high blood pressure. They tried to take her off her Ned's last week but it shot up again so she's back on. She's only 22 and never had this before. She's lost her baby weight already. She is still having headaches, tingling and numbness on the left side of her head. She did have an epidural too. Just wondering about the possibilities and or dangers?
