Risk lists tend to blur into everything is a risk. Two factors stand out here, age and smoking.
Who does the evidence point to?
Each of them comes with a published statement. The first is anyone getting older. OrthoInfo (AAOS) says: As people age, the water content in the disks decreases and the disks become less flexible.
The second is smokers. WebMD says: Smoking is a major risk factor for degenerative spinal diseases.
Reading the two factors side by side
Age is the factor you cannot change, and it asks nothing of you but attention. Smoking is the one you can change, though quitting is a decision with its own cost and staying power.
Treat any rate, age cutoff or ranking of the two factors with caution unless you can see who published it.
What to do with this
If you are in Little Falls and either factor fits you, bring it up at a visit. Ask the office what an evaluation costs and what its terms are before you agree to anything.
Further reading helps you form questions. WebMD's pain management center is a broad starting point. OrthoInfo's sciatica page covers leg symptoms. The American Academy of Pain Medicine describes the specialty, and the Cleveland Clinic's pain management overview lays out treatment types and their trade-offs.
A practitioner's note
A short list you can verify beats a long list you cannot. Use these two factors as prompts for a conversation, not as a diagnosis.
