I have cervical/lumbar spinal issues (stenosis, degenerative disc disease, myelopathy, osteoarthritis, neurogenic claudication) and small fiber/peripheral. It affected my head, neck, shoulders, back, arms, hands, legs and feet.

It seems you may have issues with spinal cord/nerve root compression (may be from disc/bone spurs/vertebrae issues) that radiates and shoots electrical shocks to your upper/lower back and legs.

It would be good for you to see an orthopedic spine specialist and/or neurologist for MRIs of cervical and lumbar spine. They should be able to help give you options for treatment (pain management, nerve pain medications, spinal injections, PT) based upon diagnosis.

You will want to be careful not to fall or get chiropractor adjustments which could worsen symptoms (especially if you have compression of your cervical spinal cord). I do not believe taking supplements for your symptoms will make a difference (they help small fiber neuropathy if diagnosed through neuropathy bloodwork/skin punch biopsy) but do little for your spine. Supplements for osteoarthritis/inflammation and change in diet to reduce inflammation may help if diagnosed.
