I have the same problem, I have been ignoring it but it is a pain, some times it take great effort to ignore, seems like drafts and moisture condensation maybe, I am unsure but man it can get to be a pain.
maybe some cream or freezing salve would work, anyone tried it?
For me it seems to be a psychological thing. I had it for the first few weeks but now it seems to have gone away. I think that knowing I can't rub my nose leads to an automatic desire to do so. I have noticed this when I go to the dentist. The minute the dentist gets me in the helpless position with tools in my mouth, I have a overwhelming need to rub my nose.
Good news is I had forgotten all about it...until now...
I had the same problem when I first started using my cpap mask. A lot of the time it turned out to be a kind of 'nervous tick', that goes away if you use your cpap enough.
Hi Matt! Welcome to the site. How long have you used CPAP? Is it working well for you?
I have a similar problem. When I first put on the mask and turn on the CPAP, it feels like little pieces of lint land on my nose. I don't turn off the CPAP but I do unclip one side and reach in to scratch the annoying lint away. Recently, I added the fine particle filter to the regular filter and this issue has greatly reduced.
Hope this helps. I tried the Zen method to ignore and it is impossible for me - so far anyway.
