Well my husband didn't have a herniated disk, but a bulging disk. In his lower back.
Both are degenerative however.
He got physical therapy. After seeing his specialist.
And it helped him.
He was experiencing pain and numbness in his legs from it.
Surgery was not a HAVE TO. It was an option for him. BUT his nerves were being rubbed, rubbed away from his bulging disk. He did eventually have surgery. It helped. It was not fused or anything.
You should see an Orthopedic Doctor.
Not your Internist.
My Husband saw an Orthopedic Doc and a Neurosurgeon/Neurologist for his, diagnosis and follow up care.
A herniated disk is like a blown out tire.
Your Internist, should have... referred you to a proper Specialist.
An Internist, is not the one to see.
Your Internist.... is probably just referring you to the Chiro in his office... because it is convenient for him, and is in his office and they are "partners?"
So to me, that is not an objective... referral for your medical issue.
You need to somehow, take time off to see an Orthopedic or Neurologist. To get a proper diagnosis and recommendations, for your spinal problems.
The pain and tingling you are experiencing... is due to nerve damage or nerves getting tweaked. See a Specialist, before it gets worse.
