Pinched Nerve?

About three days ago I woke up with pain in my lower back and hips. It wasn’t great but manageable. Then the pain shifted to my left ass cheek. I started getting numbness. The numbness and pain is still persistent in my butt, but also started radiating down the backside of my left thigh. I got no sleep the next night. I got up yesterday with my kids and the discomfort was so severe I could only get relief by laying on my stomach on the ground. My husband sent me to our room to rest. About midday the numbness and pain started expanding to my right butt cheek. I did manage to get a couple of hours of sleep but nothing consistent and the pain is increasing. I live in a tiny nothing town with no insurance.

Things I have been doing to mitigate:

-Heat/cold on the area Light but consistent -stretches/yoga Anti inflammatory pills (ibuprofen/tylenol) -Taking a low grade muscle relaxer from a previous ailment, this is the only way I have been able to achieve sleep

I am planning on going to a chiropractor today to see if an adjustment will help but as each day passes and my literal quality of life diminishing, I don’t know if that would even be helpful. I am not opposed to seeking medical care but I truly don’t want to go and pay for scans to only be told to rest and do what I am doing.

I understand without seeing me it would be difficult to say what is going on but does this sound like it’s presenting as a pinched nerve? Is there anything I should be doing more of or stop doing?

I can barely walk. Even on my stomach the pain is present. Nothing is helping. I am desperate. Any guidance would be incredibly appreciated.
