Chronic Nerve Pain - central pain

Are there any emerging treatments for burning nerve pain ... also "rivers of electricity" running through body ... feel like plugged into a grid.
More pronounced after after bending forward for a time to read/write/use computer ... Also difficulty judging accurate placement of feet/hands .. need to give attention to the movement to direct a more smooth/less clumsy outcome ...
This has slowed overall function to 1/3 of previous .. plus fatigue factor with more "consious" parallel processing instead of relying on feet to walk when you decide to .. getting harder to push up from sitting and walk .. I push onto stick with one hand .. other surface with opposite hand ... then when standing consciously steady myself before stepping forward.
Typing hurts fingertips and all surfaces that skin contacts ... both burning increased and pressure of limb weight. At times my legs feel too heavy to walk up stairs with .. puffing by the top.
Have L3,L4,L5 disc protusion/changes .. But also iintial L shoulder injury which recently hurts right  round top of arm/torso with arm moves .. esp with  reach/carry.
Neck is primary area - fused C2-C6 [spontanous screw migration 2yr after non-stable  C3-C6 fusion] ... 10 yr later again unstable, so 2005, C5-C7 fusion+laminectomy to free damaged spinal   cord.  Burning, allodynia, parasthesia have increased in spread/extent/effect on function and  pain "noise" interference with clarity and speed of cognitive function.
Recently burning even in scalp, feel roots of hairs, and top of back, front torso neck to solar plexus area burns. Saliva dries up and nasal mucosa, eyes searring even fogs my glasses sometimes. Feet hand legs arms neck lymph swelling-some relief if laser 900mu weekly & daily self massage[hard w allodynia].use hypnosis,meditation, brain wave entrainment,acupuncture.
