Severe lower back pain 8 weeks

Leah
I am 8 weeks today. Since yesterday afternoon, I am experiencing severe back pain mostly in my lower back. The pain radiates up and down my spine and feels like it's on fire. Part of it has seems to be somewhat related to being gassy. 
This is my second pregnancy. With my first much of my back pain came in my 2nd trimester and was accompanied by back labor which sucked. 
Any suggestions on our to cope? Should I see a chiropractor.
