Talk to Gynecologist on Twin Pregnancy

I had two doses of betnisol injections last week because of complications like low liquor amni of fetus 2 which may lead to preterm labor . Since then, i am having insomnia like I cant sleep properly, i have dry throat, if I consume water then my stomach gets heavy and I have trouble breathing. I cant lay down for more than one hour hardly. Are these side effects of steroid shots or is it normal? Thank you
