hi IM MALE 39

for the last 3 months been having back pain when i sit up straight and sometimes when i lie down mid back, last 4 weeks constant pins and needles in arms and HANDS feet, (MANLY WHEN IM A SLEEP THOUGH IT CAN WAKE ME UP)- left leg back of leg cramping sometimes pains at end of fingertips, and in big foot, just feel tired all the time no energy.. could this be MS?

all bloods came back clear
but ive not ha a fasting diabetes blood test,

yesterday i saw a private neuro consultant, he has but me down for a mri neck and head and a nerve conductivity test

all the symptoms i put into google come up with either brain cancer or spine cancer im worried sick i just fear the worst is going to happen!!
