The descriptions you were given are not helpful to understand what the MRI identifies. “Osteoarthritis” is a poor non-descriptive term for degenerative changes of the spine.
I do not understand what “dropped down” means. I am assuming your physician is referring to L5-S1 as that level is the “lowest lumbar disc above my coccyx”. He or she could be referring to a disc bulge, tear, herniation or even a spondylolisthesis.
No matter what he or she is referring to, this disorder will not “move back” in two to six weeks but may become asymptomatic (non-painful).
