Does anyone else take ibuprofen daily? I’m worried I’m wrecking my kidneys.

I have a severe disc herniation and a nasty bulge in my lumbar spine causing severe spinal stenosis. I’m been taking 1200mg of ibuprofen daily ( for a bout half a year) because it helps with the inflammation. The difference between taking it and not is extremely noticeable… Regardless my pain is horrid and i’m practically bed ridden. Doctor refuses to prescribe me literally anything for the pain. I do see a neurosurgen in just a week, so hopefully an ESI or surgery is soon. I’m honestly so scared I’m hurting myself by taking this medication everyday but if I have literally nothing else at the moment. I’m otherwise relatively healthy, but i haven’t had bloodwork since i started taking it daily so maybe that’s changed.
