Hi,

Back pain in life as it is in golf is usually about poor posture that means you have recruited muscle in an asymetrical fashion (one side being shorter and tighter than the other) this can also be true between the front and the back. Much back pain can be due to poor stomach muscles - your core. Coincidentally your core - Transverse abdominus, Internal obliques, rectus abdominus and external obliques come on (or not) the moment the club leaves the ground at address. If you have poor abdominals your back will be compensating. As you are so tall you are naturally creating more torque in your lower back than other shorter people.

Listen to no one until you have been given the all clear by a physiotherapist not a chiropractor. Some diseases of the spine/discs can be made worse by exercising. Check it out first and get back to the forum if you wish. You can also look at getting Chek practioner to help. I seem to remember that they are listed on the web at the Chek institute - even all the UK based personel.

Hope this helps.
