Unbearable Lower Back Pain After Long Car Trip

I’ve had some lower back pain that radiates down to right foot off and on since I had a baby February 2021. Took a 10 hour trip via car and by the time I arrived , I could barely walk bc the pain in my lower back and right hip and butt was unbearable . I’m no stranger to back pain as I’ve had 2 ACDF surgeries to c5 thru c7. This pain in my lower back and hip is unbearable . The trip was June 16 - 19 and we traveled 10 hours back home . One wrong move and I’m in horrible pain . It got so bad last night, I was unable to sit up in bed and the shooting pain brought me to tears . I actually peed my pants , the pain was so bad . I’m using a cane and taking ibuprofen and BC powders for back pain around the clock, but nothing is helping. I have a 16 month old that depends on me as well as husband and 14 year old . My oldest has been a big help with the baby the last week . I’m so worried it’s a slipped disc .
