Horrible aching in my arms and back

I'm 16+1 weeks and I woke up at 330 this morning in so much pain! I'm still in pain and hasn't gotten better and it's 7 am. My arms and hands ache like as if I was beaten up and my upper back feels the same way. I'm not sure what caused this but I need advice and I need relief.. It's unbearable. I do have a large chest.. I'm a 34F and I'm wondering if that's what's causing it because they are so heavy... Idk but please help!!
