needing advice or suggestions

Dyanna
Ok two things...
1) any reason why all of a sudden nursing a 6 month old has turned into a wrestling match with an alligator?! She's kicking, punching, flapping her arms, trying to sit up....is this normal or is there anything I can do to help this situation? 
2) this whole week she's been waking up almost every hour, letting out this painful sounding little scream. I've tried feeding her, giving her a pacifier, and it just continues...every single hour throughout the night. I don't see any teeth cutting. I've given her Tylenol before bed (had her shots on Friday)...I'm stumped. 
Help!!!
