I suggested Forensics because it seems to make the most sense in line with those abilities. There is a body language to pain and different injuries manifest themselves with different physical characteristics - that even if you've covered up, an expert may pick up on. It could even oppose Disguise, and be an assessment tied to a command that takes some time to complete. The reason I suggest this is because I can see opportunities where, for instance;
This could lead to interesting RP where, despite showering and changing clothes, you have to be a bit more careful about your story of 'slipping while redecorating'. You can redress and show up, in great pain to that boardroom meeting you just have to attend after being shot in the gut during some shady, illegal dealing - but that Senior CorpSec agent who worked in criminal sciences may know better than to believe you've been under the weather and have severe cramps. If you're not a skilled actor, somebody with the know-how might just see through your story.
Of course, there's always the 'bullshit, lift up your shirt' route for the less savvy, but that isn't going to fly in every social situation - I think this suggestion opens up interesting avenues of RP and creates more nuanced situations than 'Covering up your wounds' being a one-quick-fix. It also awards the bullshitters for actually investing in their Disguise and the specialists who work in Forensics (or those who have prepared themselves in other ways).
This might also help squeeze painkillers into RP a little more often. If you've got a board meeting in five and you're gut-shot, popping a Dezraldin, changing your shirt, and going in like nothing is wrong might be pretty funny.
