Not sure if there are any doctors/other knowledgeable people here that want to comment.
I hurt my back - got an MRI and Pregnisone - waiting for the second appointment with the doc. My back is better with the oral Pregnisone but has now leveled out and not getting much better if any. In the mean time I thought why not look at the MRI images.
Not sure which pad I'm pointing to maybe 5-6.
