I have nodules growing on quite a few fingers. I did see a rheumatologist and was told it's osteoarthritis.
I don't tolerate anti inflammatory tablets but what does work for me is Voltarol 12 hour gel. I've only recently tried this and it's so good. I put it on my fingers at night before bed and it really eases things.
I'm on HRT but it doesn't touch arthritis pain at all.
