Hi, I m a 30 year old female 5 4/110 lb. and have had 3 epidural lumbar injections over a 3 month period. I did not notice many side effects with the first 2 injections, but after the 3rd I have lost a lot of muscle, gained weight, became more irritable and tired, and noticed changes in my menstrual cycles. (without changes in my diet/exercise) Approximately how long will it take for these side effects to go away and my body begin to feel normal again?
