I have a spondylolysis in my lumbar spine. what can i do to relieve the pain?

Depends: If it is an acute spondylolysis, a period of rest, perhaps a brace, and mild exercise may help. For a chronic case, physical therapy concentrating on core strengthening (stomach and back muscles) and aerobic fitness often work. Surgery can help if other, simpler measures do not give enough relief.

Spine defect: Spondylo means spine and lysis means crack. These can be congenital variety which is genetic in origin occuring in 6% of the us population or after trauma which can be repetitve particularly in certain high level athletes like swimmers, gymnasts, pitchers, football linemen to name a few. Most are treated non operatively with bracing, physical therapy & medication and activity modification.
