Thank you for your question.
findings provide guidelines for treatment but the treatment decision is primarily based on your symptoms. Disc dehydration
is a natural phenomenon that occurs with age. Disc bulges are commonly seen on MRIs of middle aged individuals even in healthy population. If you had only the lumbar findings playing badminton is absolutely fine. The finding that is of concern is at D10-11 and extent of compression needs to be evaluated before further decision is made. Again, as I said the treatment is guided more by symptoms than MRI.
Please let me know if I can be of further help.
