Update on paddys condition - help please

Hi I'm very sorry it's been a while since I posted but here's an update on paddys condition. I had him castrated and at the same time x-rayed to find out the problem with his back legs, it seems his hip joints are squared off rather than rounded so he's got severe arthritis in his hips. As for the weakness in his legs he has got pressure pushing on his nerves to his back end from his spine that is causing his nerves to basically deteriorate. I've been prescribed rymadil for him and I give him tablets for his arthritis to help with ligaments and joints as well, is rymidal as bad as I've read about it? Any advice is appreciated
Thank you
Alex and paddy

I have moved your post into the health area as more people are likely to see and reply to your question here - I hope you don't mind

I'm sorry to hear that Paddy is having trouble with his legs.

Unfortunately this is not something I have had any experience with so I am unable to offer any advice, however I am sure someone who has will be along shortly.

Hi Alex, sorry to hear Paddy is poorly  Poor thing. Unfortunately I'm not familiar with conditions like this and the medication that goes along with it, im sure someone will be along shortly with help.
