If you are genuinly sick, press 2.
Then phone the FDM and tell them the situation.
Then phone the clinic and see someone (nurse/doctor or local hospital with referral).
The company will not punish you if you really are sick, it's the gutless B's who use the system for their social life who they want.
They can't afford to have you turn up at HQ and then go sick, just to avoid an absent day!
The FOM hasn't changed, you are still
LEGALLY required to go sick if you are not fit to fly whether that's 10 days or 10 mins before duty.
Safe flying
