Well Degenerative disc disease
is not something for which you need to get a surgery done until and unless you have some associated spinal issue leading to triggring of red flags for a surgery, which your description does not show.
As far as the pain in the thigh is concerned get yourself evaluated with an orthopaedic physiotherapist in you area first, as he will be in a situation to evaluate you may do an x-ray if needed and provide you relief without any prescription drugs only with the help of Electrotherapy
& Manual Therapy & Exercise Therapy
sessions leading to posture correction & spinal or conditinoning.
And yes even I would recommend you to take adequate input of Calcium supplemetation with adequate intake of water 8-10 glasses per day. As discs are 90% water so dont let your body dehydrate.
Hoping for a speedy recovery
