Thanks for providing more information.
I understand your concern and i strongly advise not ignore your symptoms as such and you may require proper treatment rather than taking pain killers.
In my opinion you need to be seen by your Orthopedist again or neurologist can be considered for a clinical examination and undergo MRI of Lumbosacral spine,Nerve conduction velocity test with EMG to rule out underlying possible causes like Herniated disc,Lumbar radiculopathy,Bursitis,Fibromyalgia,Autoimmune arthritis.
Physical therapy can be effective in your case.
For severe pain,steroid injection,pain patches can be advised.
I suggest you to make an appointment with doctor and advocate yourself regarding your pain.
I hope this helps.
