Hi there, This is Dr Basu, Experienced Specialist. I am here to address your concerns and provide great service.
Dark brown urine suggests bleeding in the urine.
Can be from the bleeding from bladder or the kidneys.
Also kidney stone can cause such pain and dark brown urine.
Ibuprofen is a medication causing bleeding.
It is better to get kidney ultrasound.
that will rule out any kidney damage, stones.
also a urine analysis to rule out any infection.
you should avoid ibuprofen for now.
that can be kidney related as well.
Another possibility can be herniated disc in lumbar spine.
that can press on the nerve root causing severe pain.
Your GP can easily order an ultrasound to check your kidneys out to set the ball rolling.
If the ultrasouns is normal --then good.
you need to see a spine specialist in that case for MRI scan of the spine.
you can see a physical therapist.
physical therapy is the main treatment anyway
He can recommend a MRI as well.
