EXTREMELY PAINFUL CRAMPS!

So since I was about 13 now 20 i’ve had EXTREMELY painful cramps during my period. We have tried everything heat, high dose of meds, hot bath with epsonsalt, massages, shock therapy, etc... nothing works! it continues throughout my entire period but is at its peek during the first 3 days!

I get pain in:my hip bones, lower stomach,

lower back, in my legs, all my joints, and headaches. I get dizzy, nauseous, sometimes even hard for me to breath. If i eat or drink anything it makes it worse. All i can do is lay there and scream and cry in horrible pain! I miss work becaus of it. When i was in highschool i missed so many days because of it i almost didn’t graduate.. But ya girl did. For years me and my family have been tryinng to figure out whats going on and why is it like this? Any help as to what i should do or even a hint of what might be wrong with me would be amazing!
