Hi, Welcome to Health care magic forum.
As you describe, you had numbness
of shoulders , back, and legs.Tingling
of arms, and legs. You had surgery on brain, and back.
I advise you to consult a neurologist
for diagnosis and treatment.
I usually prescribe to my patient with such symptoms neurotropic injections for 10 consecutive days,and then periodically,calcium suppliments, and pain killers.
Avoid taking potato, other tubers,tomato,egg, chicken,and and sea foods.
Wishing for a quick and complete recovery. Thank you.
