Labour?

Its 10:58 pm rn so lets say in about an hour I am 36+4.

Since Saturday the 22nd I’ve been having worse lower back pain than usual but nothing to concern me too much. Since then it has actually been intensifying every day and today the pain has gotten so unbearable at one point my husband had to pick me up from the toilet seat and walk me to bed because i couldn’t walk or get up alone without feeling like I’ll fall. Its like all my nerves are on fire? Since then i am able to walk and move on my own again but i cant bend my back in any way not even a bit, when I lie down the pain doesn’t go away it keeps throbbing and honestly keeps getting worse. No pains in the front yet although i may feel

Some tightening? Idk even know how that feels like as this is my first pregnancy. Started feeling a bit nauseous before too but it went away now. Should I go to the hospital or suck it up? If its sciatica lets just say i have the worst case of it ever.
