After a fall in 1988, I have now had more pain in lower back at L5 etc. My new doctor has started me on physical therapy 3 x week, a new drug call Lyrica. He has ordered a new MRI and I am scheduled for an EMG. My question is the Lyrica. I feel like I am dizzy and staggering, and I have dysfunction of my thought processes - I can't seem to remember even the simpliest of things and then, just as fst I remember them. Several people I have spoken with said they have had these same temporary reactions and others. They say this should go away in 2-3 weeks. I am not sure - has anyone else had these symptoms and should I be concerned. I am told I must get my back in shape as I am also scheduled for 2 knee replacements. I am 70 and in good health except for arthritus, back and knee pain and problems related.
