Handshake or not??

[CHUMMUM]

Hello, I don't post very often but thought I'd ask wise mumsnetters for their opinion on this one.
I have Rheumatoid Arthritis, it affects my right hand a lot so I am terrified of shaking hands because any squeezing and I'm in agony.
I have an interview next week, my 1st for 20 odd years!
I was going to explain I can't shake hands as soon as I go in or offer my left hand, hubby says it will get it off to bad start if I do any of these and I need to grin and bear pain!
The only other thing I can think of is to explain before I go, the lady is ringing me to discuss day/time of interview either later today or tomorrow.
Has anyone got any suggestions and if you were an interviewer would it put you off me??
Thanks in advance.

Could you tie a bandage round your hand? Then if they go to shake hands you can sort of wave your bandaged hand as if explanation for why you can't? If they asked you what was up with it, you could then explain it's just to protect your hand because of the arthritis?

It wouldn't put me off as an interviewer, but I just think it means a potentially slightly awkward conversation for you when you go in, which is when you obviously want to be creating a good impression.

Thanks red, I was worried that the bandage will make them think I'm worse than I am!
I'm right handed so that is probably why my hand is always swollen!
I use it all the time and sometimes it can be painful but I manage.
Would I be okay to mention it when she rings me tomorrow so it is out of the way before the interview and I can try to wow them on the day?
