MRI Resuts interpreted please

First I would like to thank you for considering my questions.  I have had 2 back surgeries. The first was in 2004, and the second was in  June207 to remove the majority of the herinated disc at L%.  Due to my finanial situation, I am not able to recieve quality medical care.  If I list the results of my MRI, can some one please explain them to me.  The MRI was taken on May 9.  My back pain began to reoccur after I fell down some stairs in December.  The pain is getting worse and is impeding my daily functions.  Any explaination or suggestions would be appreciated.
