uncontrollable shakes

Grace • Zion James 1/22/17, Kingston👼🏽 10/14/18, rainbow baby due December 19’🌈💕
I gave birth on Sunday. The whole time I was in labor I had terrible tremors and even afterfor a few hours someone had to sit right next to me while I held my son because I was shaking so bad. Well it finally calmed down and went away. Now today, I'm shaking just like I did in labor, I'm not cold or anything I'm just shaking, and my muscles tense up and so when I try to walk my legs give out on me. Anyone get the shakes again AFTER birth??
