Arnie: thanks for your advice re the physio....my appointment is in 3 weeks, with the chance of a taking a cancellation to make it earlier.

Jen: Has anybody told you that you're a wonderful woman? Well they should, 'cos you are! The information you have provided me with has prompted my to send out enquiries to the local horse doctor / equine type suppliers. Watch this space! I don't take a vitamin C supplement, rather I rely on a vitamin C rich diet...loads of fresh fruit & vegetables.

Cheers,

John
