M58, have severe back pain when stand up from sitting after that its fine. is this herniation or slip disc. also general joint weakness pain all body?

Back pain: Pain that is worse after rest, but better with activity tends to be some kind of a degenerative or inflammatory condition like vertebral disc disease, or disc degeneration. A herniated disc would tend to have some kind of symptoms that radiate into the leg. Sounds like a general rheumatological workup including some imaging study of the lower spine is something to consider.
