Vit d got me thinking

Hi, I went to the doctors last year for stomach pain. He ran full blood tests etc which came back fine apart from low vitamin d levels. I’ve had eye pain off and on for several years with 2 occasions of blindness for around 10 mins, fatigue ( which I put down to shift work ) I get pins and needles in my hands and feet but I’ve always put this down to my physical job and lots of cycling. Now with the low vit d level it has me thinking possible ms… one of my parents has ms which I know isnt hereditary. Is vit d a sign of ms or is it common in people without ms? I’ve got to have another blood test to check my vit after 6 months so another month so maybe I’ll bring my concerns up with the doc. Bit of a ramble but I think I’ve been ignoring my bodies signs and time to get it check out.
