Hi Gone through your query. This is typically pain due to spinal stenosis a condition common in this age group. It is better to take some rest when the pain starts after playing . Also try to avoid playing continuously for long time . Try to take short breaks for rest in between short of the pain threshold periods. Bending forward while taking rest is one way to get relief of the pain . You can also get relief by lying on back and pulled your knees upto the chest . Meanwhile take Ibuprofen or diclofenac tablets for pain relief . Make sure you are not allergic to one of these medcications . If you are on any other medications for any other illness then better to discuss with your doctor to avoid any interaction between different types of the medicine . It is also advisable to get an xray of your spine done at sometimes to see the degree of narrowing the spine and compression over nerves . Feel free to ask any more questions or to clear your doubts . Thank you Also
