I have a herniated disc in lower back.Been dealing with it for about 7 yrs 3 of which have been chronic. I had a series of 3 shots in 3 weeks one year ago and had instant relief for about 2 months. My pain came back after this short pause with a vengeance. I just went back to the doctor for my second series of 3 shots but he really knocked the hell out of me this time. I have had a accelerated heart rate, puffy face, huge weight gain, anxiety, insomnia, incredible appetite, cotton mouth and some digestive problems as well. One good thing about it is that I do not have any pain(for now). I am scheduled for surgery in a month hopeful to get away from all drug treatments.
