nah.. PES E are for those whose condition, when triggered, is
not life-threatening..
yours may be.. SAF is just washing their hands in case..
i knew someone who had a heart murmur, they found that out after
BMT and halfway into SAFINCOS (what we call SISPEC now)
he was medical boarded, later given PES F then discharged.. from
what i heard, he then went to uni immediately after and got a
job..
don't worry lah.. the most, call up any bank HR right now and
ask them if they need the COS.. or if they have any criteria about
health problems...
good luck
