5 years after a prostatectomy my psa has risen from a steady 0.06 for five years
to .1 over the last 4 months. Over that time I have had a cortisone shot in my shoulder and (3) sets of shots for nerve pain in my lower back. Also was given Gabentin for about six weeks to see if it had any effect for nerve pain. Question is it possible that any of these lower back treatments could have effected a rise in my psa?
