any suggestions?

For the past week or so, the base joint of my right-hand little finger has been very sore, particularly on the palm. Range of motion is generally normal, except immediately after waking; at that point, the finger is "jumping" between different positions along its length (bent/partially extended) as I flex it, accompanied by a general feeling of thunk. This gradually wears off over the course of half an hour or so. Sensation is mostly normal (if slightly tender).

Potentially relevant things to consider: hypermobility-type EDS; RSI.

Suggestions/input/advice welcome; I have not yet tried sleeping in wrist splints but suspect that's my next step.

Since this worked so well last time :-)

I have a coat. I like my coat. It is Goretex and generally useful. It also, alas, is down one bit of kind of important tech for the zip.

Specifically, it has a separating zip, and at some point the zip box has vanished into the ether. It's a YKK Vislon 5VS zip, and I'm pretty sure the box I want is 5S (that being what's stamped on the bottom of the subsidiary zip).

What I can't do is work out any way to usefully poke the internet to get it to disgorge me one of these, the obvious search terms being unhelpfully vague. I also don't trust myself to usefully transfer the subsidiary zip's box to the principal zip.

Suggestions for how to source this part in the UK (preferably without leaving my house, but I'll go to a haberdashery if I have to) gratefully received!
