Hey Bro,

Is the pain in the front or around your back?

Bro,

I had pain in my back for a long time and tried many things..osteopath, naturopath, chiropractor, acupuncture, physiotherapy and eventually surgery!

You seem to only have pain after playing? I would say try something to strengthen your back first – Pilates is brilliant and yoga too. Pilates will build strength in your back and was recommended by my surgeon and everyone else I have seen. Yoga won't really strengthen your back, but increases flexibility. I think you would notice improvements with your back pain quite soon if you tried them. Just some basic exercises and stretches can make all the difference. Many people who do Pilates and Yoga find they can do much more afterwards.

P.S What did the doctor say?

not sure why you'd be getting pain in your waist,  

my only advice would be to insure you stretch and warm up well before you begin to play or even hit a shot,

Before you play try warming up the area with a heat pack,  and when you get home after playing try having a nice warm bath to sooth and relax the muscles.

You said your friend says it's because of your movements – does he mean you're doing the incorrect movement or have incorrect technique? I'd take Paul's advice and have a coach look at you just to help with these things and look at your footwork etc.

I've already mentioned Pilates/Yoga and other exercises and they all work your fully body – especially your back and your core like mentioned. I learned a few exercises and stretches and do them at home and they've made a massive difference in pain relief – I don't really get any now during or after games. Either way, look at all the things mentioned and let us know how it goes Bro..
