I just had the 3rd block on Wednesday. I find the lumbar block to have a few side effects for me, like I feel tired and don't move very well the day that I have the shot. The last time I had it I felt really horrible for 2 weeks, but the doctor said it was because he hit the nerve wrong. This time it is kind of painful in the hips still, but it was given in the siatic nerve and hopefully in 2 weeks the pain will go down as far as it did the last time. Except this lat time I had a flat tire the day after and I am still feeling the back, back talking about why I should of not bent the way I did.
