Hi Pamela, (As I typed your name I found myself pronouncing it a la 'Smithy', from the BBC's 'Gavin and Stacey', – 'Pam – El – Ah). 🙂
I haven't really looked into it yet (I either like surprises or I'm a fatalist… 'I'll deal with it when it arises') but I too have been told that I will need 'pins' – one in my upper left arm and one in each of my upper and lower right arm; plus one (apparently the 'important' one) in my left femur.
So while I can't help you with your inquiry I will follow the responses here and any future development with regard to your 'nail' with great interest. :-/
That's one small comfort with this blooming disease – you can be guaranteed the answer of 'No, it is not!' to the question, 'I thought it might only be me'. :-S
Good luck with your inquiries, your procedure and your recovery – I would be grateful for any reports of your progress.:-)
Regards
Dai.
