Depression (as of yesterday, apparently in a severe form) and hyperhidrosis. The hyperhidrosis tends to bother me a lot more than the depression since I actively need to watch what I'm holding, touching, or wearing (certain textures will trigger the hyperhidrosis and wearing those textures for long periods of time causes swelling via hyperhidrosis). It gets very annoying, and the uses for it are... situational.
