Spine Injections

Ive had a MRI and have spinal stanosis and they want to do injections.most people I talk to say the injections help with the first one but it don't last long.I've been home for 2 months and this last week I am feeling a bunch better.I also have muscle Atrophy from trucking.sometimes I don't get out of the seat for 8 to 9 hrs.They say Ginger helps with arthritis. Has anyone tried it?
