Just a brief follow up to thank all for your suggestions to help my old guy! I am very pleased to state that I started him on METACAM 3 days ago, and today I saw a big change in him, the limp is 75% gone and he moves out in a whole different way. I have ordered the Ester C and will start him on this as soon as I receive it. Thanks to all!

I would be very careful with the Ester c as it contains calcium.
