I no longer know where to post this so it's going on Lupus website too.
Anyway, for about a month, among all the other weird goings on on my hands and fingers, I have noticed an increasingly hard bumpy patch on the tip of my index finger which is also extremely painful for such a small thing. It has redness inside, a bit like a chillblain. It's not going away and feels like it's getting more bumpy . When it's wet, after a shower or washing my hand, bits of it look white, almost like a burn.
Could this be the beginnings of a digital ulcer? My Raynaud's had calmed down a lot but lately I've started to get glue fingers regularly and all it takes is for me to touch something cool or for me to be cold and my fingers on right hand start to tingle and go pale - not as bad as they used to - for example hanging up even slightly damp washing in the airing cupboard and bizarrely when drying my hair.
