Got a doc's appt on monday, but always good to ask STW...
for a while now, maybe a few years, just below the outside of my right knee, a patch of skin has become numb. I can feel pressure if I press it, and I can feel hair moving, but if i touch bits between leg hair, i can't feel it.
I've had a numb bit the other side of my knee, on the same leg for decades, down to injury from a RTA, but that doesn't have any other weirdness and this is different.
the area has got a little bigger now, maybe a patch 12cm long by about 2-3cm wide and recently, when kneeling it feels like kneeling on glass, or rather, the skin feels like it shattered, and I'm kneeling on the shards.
Last week it was really quite bad, but this week there is a very dulled down version which is barely an inconvenience.
any ideas?
What timescale are we talking about? Did you first notice this morning, or has it been weeks?

I just re-read and saw this, no worries
My r/h calf used to do something similar. The best I could describe the feeling was almost of pins and needles, or as if I'd put a freeze-gel type thing on the muscle, and it would very often happen when I was moving around doing stuff like drying dishes. It didn't inhibit movement in that leg at all and would last for several minutes or longer before going. It must have been over a year that it kept happening - long enough for me to start worrying about it, and get around to talking to a doctor who couldn't find anything and suggested it might be down to a deep scar at the top of my leg. and then is stopped. I still have the scar. I still dry dishes.

I had this the other day, like cold running water down it. very odd. not had that before. These changes are why I'm seeing the doc. Numb bits that don't do anything are ignored, as I've had a bit like that since I was 13. OK, it's in a slightly different place, but the sensations I'm getting are relatively new, say the last few weeks.
Numbness, odd sensations/tingling all point towards something impinging on the nerves which run through that area. Pain on kneeling - maybe prepatellar bursitis - used to be called 'housemaid's knee'!
Worth getting checked out because there are a few underlying conditions which may manifest with odd peripheral nerve sensations.
