In lots of science fiction, people have EVA suits which automatically preform First Aid or administer temporary medical help (such as painkiller injections) so that they can get themselves to a safe, pressurized environment before passing out.
Now I know this isn't the case with current EVA suits but what contingencies are planned for medical emergencies / nuisances on EVA besides getting your EVA partner to bring you back to the airlock (Abort EVA)?
Do you break off the EVA half an hour in if you get a headache? Do the EVA suits have an Aspirin dispenser in the helmet? Has anyone ever vomited into a helmet on EVA? Are there any documented cases of people getting sick on spacewalk?
Note: I'm aware of this question but I'm more interested in minor sickness or illness during spacewalks and not depressurization.
