Thanks to all who have responded up to now.

My dad refused to use NSAID's, but unfortunately he ended up fused.

I must say though overall he is in good health. He is 70 now and he has obviously had no stomach problems, due to his refusal to take tablets.

I would like to be given the chance to try anti TNF blockers in the future, but there is likely to be a funding issue here in the UK. People don't usually take out private medical insurance, as the national health service should pick up the cost (it often won't though if the drug is expensive). I recently enquired about private health insurance but there is no chance now!
