Hi.
Im sorry ur suffering from this problem.. Vit d and b deficiency are rare at ur age... The probable cause might b ur posture, inadequate back exercise causing back muscle strain...
I would advise u to an orthopedic opinion to examine ur spine and once ur pain reduces, a exercise routine for ur back.
Hope this answers ur query..
If u have any more questions about this pls do not hesitate to ask me...
