I've had similar sensations that vary from ticklish invisible hair strands to tiny bites to little zings of itch. If the tiniest gnat lands on my arms I definitely know, but sometimes nothing is there at all. It's so strange. AnneDee, I've never considered pollen but I bet our overly sensitive skin would feel that too.

Drew, I have similar sensations as soon as I step out my front door if my lower legs are bare. I feel like gnats are biting me (and they very well may be) and I start to feel itchy. Maybe it's pollen. Now I never go out with bare legs. If I have a robe on in the house, I get the same sensation from the lower edge of the robe touching my skin. I think all of the scratching I did in the past has really sensitized the nerves. I don't scratch much anymore and I see the sensations improving. So far, refraining from scratching has helped me the most, but that's no surprise. I'm not 100% sure of my diagnosis...no biopsy. I have some nodules, mostly erythematous papules (that appear the day after I've scratched an area) and lichenified areas. I'm doing a lot of research to try to figure out why my skin, which never caused me any problems, is now causing me loads of problems. If I find anything of value, I will gladly share here.

Try castor oil it is working for me!

Isn't neurological issues fun with a rare skin disease? No sarcasm there... I personally had neuro issues before PN did a full- blown on me.
The spider effect feels weird to me, but it's also a warning that neuro electric 'zinging' feeling could be on its way.
I just started Nemluvio on 04OCT24, and I'm hoping it works on that for me.
"Better than to think that way"..? No, I believe you have a good head on your shoulders and thinking things thru. I'm sorry that you took have PN, but I'm glad you're here with us! Lots of information under the Resources tab.
