For spine diagnostics, MRI is necessary...Ensure that you maintain an appropriate posture while working or sitting or walking....Take frequent stretch breaks and drink lots of water...Discontinue using pillow while sleeping straight...Do not lift heavy objects, especially after bending down....Eat a healthy wholesome meal which should satisfy your minerals and proteins requirement...take over the counter pain medications.. Consult nearest orthopedic surgeon they will do the needful.
I can understand your concern.
To be really honest, this history is very very little to say much altough a list of peobable diagnosis can be made.
A detailed history and some tests will definitely be required.
Kindly consult a orthopedician in person for further evaluation and management.
