Apologies in advance for not describing this very well.
For the past month or so I've had these weird, random sensations all over my body. It's not exactly like pins and needles. More like as if someone has a small group of fine needles and they're piercing the skin. I react as one would an itch, but it's definitely not an itch.
It can happen anywhere on my body, not 24/7 more like an hour "episode". There are a few spots where it's repeated- left nostril (I know..) various points on hands and even in my eyes 
It's not painful as such but it's annoying because it looks like I'm itching randomly and I'm conscious of it.
Can't say it's when/after I'm doing xyz, just random. I'd feel a bit silly going to GP as there's nothing to show and it's difficult to describe!
Grateful for any suggestions. Off to bed now, will check tomorrow so not ignoring
