Reassuring: Your MRI is an excellent test to reassure you that there is nothing seriously wrong, like cancer. Multiple Myeloma is a cancer that affects older adults and it is not known to run in families. Your bulging disc does not usually need surgery. You should do well with rehabilitation for your weakness and pain. An EMG test (see a Physiatrist for this) may guide your care and progress.
