First of all i suggest you to don't panic and be calm .
As you being nurshing staff and have to lot of pushing work like you said it is little bit aggrevating factor for you lumbar problem.
menopause agrreavte more this. Pain can be factor which can be for long time as bones are getting weak, calcium deposition is very less and degenerative changes occuring.
You should avoid heavy physical work specilly phushing exercise where your spine get in position of curvature.
Take calcium in means of tablets which help in calcium deposition. (60000IU need per 6 monthly).
Need more best rest for your disc buldging.
Prognosis is good but not better after some treatment for degeneration.
You have to be strong and generate will power which help you to fight with condition.
