Can you tell me what are available treatment options for herniated disk at c6-c7?

There are a few: Non surgical treatment includes physical therapy, oral medications, traction and epidural steroids. Surgery includes disc arthroplasty(artificial disc placement) or fusion of the affected levels.

Usually no surgery: 90% of disc herniations get better without surgery. Treatment includes: activity modification, medication, physical therapy, epidural steroid injections, and time. Not all need to be done. In those that do not get better or have significant issues like a muscle weakness or symptom progression or bowel/bladder issues, surgery has a 90% success rate in a nonsmoker.
