Dictionary Package
While we wait on Apple, Google, and Microsoft to add "hidradenitis suppurativa" to their dictionaries, you don't have to keep seeing the red underline. Download the fix for your platform below — takes under a minute to install.
iOS and browser extensions (Chrome, Firefox) don't currently offer a way to add a personal dictionary file — that's exactly why we've filed a formal request with Apple and are contributing directly to the open-source Hunspell/Aspell dictionaries that power browser spellcheck. This package covers the platforms where a real fix exists today.
