Hi Sue,
I was on Enbrel for almost 1-1/2 years. It did wonders for my spinal issues, but little for my hands, feet & psoriatic nails.
My rheumatologist wanted me to switch for Humira for that very fact. I've been on it just under 4 months.
All the TNFs have similar risks/side effects.
The only difference in side effects I notice between the 2 is the Humira doesn't cause me to have the dull headache for a day or two after my injection like Enbrel did. But I also have a worse insomnia problem with Humira than I did with Enbrel, which I'm hoping will burn out soon.
I do have less pain in my feet on it - hands & nails are still a pretty big issue though. But I'm still holding out with a little more time it might work for my hands & nails too.
Good luck - hope it works well for you.
