Back is in a lot of pain and I feel really sick and restless!!!

Kayluuh
So im 30 weeks today! Today I started feeling really sick to my stomach and ended up throwing up several times. I got stomach cramps and then had diarrhea also several times today. It ended up to the point that I've just been feeling sick all day and my back and hip area has been in a lot of pain, when I move i can feel like a grinding sensation! I have tried to drink water, a bath, my hubby gave me a massage and just laid down to relax but my body is hurting and it also feels extremely restless. Please help, should I go in or just try to bare through and call tomorrow?
