It looks quite strange for you to develop spondylosis
at such a young age.
I would advise you to consult a good orthopedician and get relevant investigations done like
Serum VIT D,serum calcium and uric acid,thyroid
of limbo sacral spine and CBC.
In the meanwhile take following measures
Reduce your weight
Go for long brisk walking
Avoiding long sittings
A proper treatment and managent shall make you all right completely.
