Feeling fobbed off

Wanting opinions had many symptoms which would suggest MS (my nana had MS for many years so I grew up around this horrible disease)
Had symptoms for well over 2 years which come and go but are getting worse (pins and needles, numbness,muscles spams especially in hands and face, weakness in hand, itching in legs,leg cramp, spots in vision, really weird sensations in hands and feet like my fingers and toes are crossing, fatigue, memory problems) Put off going to the doctors in fear of MS. My doctor has issued bloods and told I have a folate deficiency (everytime I go to the docs I am told I have some sort of vitamin deficiency) This was done by a text message and haven’t spoke to the doctor directly, would you trial the folic acid if so how long for before going back again. I am only showing boarder line with the folate so just feel like I am being fobbed off considering all of my symptoms, most of which show abnormal on the nhs app. I am aware this is close to the heart with my Nan and the folate could be causing some of my issues but really struggled even getting a doctors appointment and don’t know if I am being fobbed off or weather I am ‘being a drama queen’
