If at all possible can you attache a photo? I could really help you with this as I'm an oculoplastics and orbital reconstructive surgeon specializing in lids, adnexa, orbit diseases.
how long has it been there
how large is it?
what does it feel like? pain, no pain
is it flat, bump, ulcer, vascular?
is it on skin of eyelid or on undersurface of eyelid?
you can take on phone and send to and i'll try to help
a small blood spot that is painless and flat likely represent a small leak from a highly vascular lid capillary. should get a bit larger over 48 hours and then slowly regress over next 10-14 days and then resolve.
