I am sorry to hear about your sufferings.
You may have advanced osteoarthritis of the left hip joint.
Also lumbar spine arthritis is also a possibility.
MRI scan of the hip and lumbar spine are required first.
Intra articular steroid injection will be beneficial.
You should see a pain specialist for this procedure.
Oxycodone is an addictive medication.
Hence, long term use is not recommended.
There are other non narcotic oral medications to control your pain.
Gabapentin is one such example.
Nortriptyline also can be used.
