My husband, who has chronic health problems which mean he has little mobility, has over recent months been experiencing a strange thing. The doc reckons maybe arthritis. Sometimes his first and second fingers lock together, quite straight. There's no pain. After a few minutes or so they relax again and 'act' normally. It can happen on either hand, sometimes both, and only ever those 2 fingers are involved. It can happen at any time of day. Seems odd that it's the same 2 fingers which are affected on both hands. Does this sound like arthritis? We're intrigued. From the postings on this site it seems like when arthritis is the cause there's usually pain too, but he never has any.
Cheers
Jay
