Do i scream correctly?

When I ever I scream( im pretty sure I dofalse cord but idk) I make sure I use my diaphragm. But if I practice like 5 or 4 songs I get this weird feeling in my throat but the first four to five time i don't have the feeling. It doesn't hurt but it feels like there flem in the back of my throat. And it sometimes gps away if I drink something. Look up TDWPrada lover on YouTube if you wnna see me screaming. Help me out is this normal?
