Thank you for your query at DoctorSpring.com
I have read your details with diligence.
It looks from your details that you are having L4-5 & S1 facetal arthropathy & anterolisthesis at L4-5 vertebra,ehic means that you are having arthritis of spine as wells anterior migration of L5 in comparison to L4.
I can understand the pain due to this.At present the treatment options for these complaints are-
-Wearing a lumbosacral corset which helps in maintaining the normal posture & prevent progression of present condition.
-Taking help of a physiotherapist ,if condition is not severe.
-Your orthopaedic or pain specialist may inject local steroid injection at facet joints ,which will help in relieving pain as well as inflammation at facet joints.
-If all other fails then surgery is an option where your surgeon may fuse the adjacent affected vertebrae & stabilize them with metal implant.
Till you choose any option you may take a good analgesic for present problem.I used to prescribe a combination of tramadol with paracetamol for such condition with corset support.
Hope this all will help you.
With best wishes.
