I am 47 years old, male, suffering almost 7 years from:
Legs pain, buttock pain (hips and legs with contact with seat), mainly the pain is during setting and driving.
Legs pain if I stand up without moving
The type of pain is burning pain in the skin like sun burning pain. The pain increase until point that I can set any more,
To release the pain I have to stand up and start walking, I always have switch between setting standing and walking, I can’t stay in one of them more of 15 minutes ( about).
Lying on the bed is the most comfortable position for me.
I was checked by all kinds of doctors (Orthopedic, spine experts, Neurologists, Rheumatology, Pain clinics, psychiatrics
Most of the checks are good:
MRI brain, OK
MRI spine ( all spine)
MRI Lumbar , Lumbar Degenerative disc L5-S1 without pressure on Nerves
EMG test twice, OK
Blood tests OK, B12=580
LP test is OK
Bone scintigraphy: OK except Lumbar Degenerative disc
Neurological sense test heat cold test, OK
Rheumatology test : No Fibromyalgia
Orthopedic leg raise test : within normal
Orthopedic doctor is not sure if my pain is from the Lumbar spine, some Orthopedic doctors propose fusion surgery L5 S1

Medicines that I tried:

Elatrolet
SSRI medicines ( Paxxat, Cipralex….)
Gabapentin, minor improve
Symbalta, medium improve
Currently I am taking: Elatrolet 10 mg Lyrica 150 X 2, and Cipralex 10 mg
It is very hard to me to work to travel and have normal life with my family.
It looks that I have neuropathic issue or / and Lumbar Issue, not sure.
I need help if anybody can advise or had such pain.
