Welcome Lisa ,by the way an advice ,I had 6-7 or more I don't even remember how many lumbar blocks for my rsd/crps pain on my right foot,well if you don't rest let me tell you,the medication won't stay in your body,unfortunately for me my dr sent me to work the next day and my job required constant stretching ,twisting,bending,etc.so far for me did not work,but don't get scare ,they might work for you,we are all react different also is a lot to learn,don't b afraid soon you will find a right combo of meds and medical treatments that would work.
