I was doing my nebs this morning and in the process of taking the cap off of the neb and putting in the pulmozyme i pinched the tip of my finger and got a papercut. Either xeopenex or pulmozyme must've got in it cause it stung like a you-know-what forever. I dunked it in a bottle of water but nothing seems to help- 3 hours later its still stinging with pressure. Anybody know if I should be concerned?
