Patients will receive continuous US suprascapular nerve block only.

Patients will receive continuous US suprascapular nerve block with oral gabapentin 300 mg once daily at bed time.

The high frequency linear ultrasound transducer (Sonosite 6-13 MHz) in a transverse orientation will be placed over the scapular Spine.

Moving the transducer cephalad the suprascapular fossa will be identified. 18 gauge touhy needle will be inserted in plane after subcutaneous local anesthesia infiltration with 1 ml lidocaine 2% Real-time imaging will be used to direct injection of 2 ml lidocaine 2% to test perineural spread of injectate after confirmation of the position of tip of needle injection of 40mg methyl prednisolone diluted in 5 ml bupivacaine 0.5% will be done through the needle to anesthetize the nerve and create space for catheter insertion. After catheter insertion another 2 ml lidocaine 2% will be injected through the catheter to confirm position perineural in the scapular notch. Lastly Catheter will be fixed via skin tunnel and secured with skin sutures and adhesive tap.
