of the face after visit from dentist
is probably due to the local anesthesia
dentist might have given you. If it is a big purple spot, it could be a condition called sub-hyaloid hemorrhage, which is not a serious condition and is self limiting. However, if the spots increase, you should consult an eye specialist (preferably a vitreo-retinal surgeon).
Meantime, you can start taking tablet Vitamic C and some anti-coagulants. You should also get a CBC (complete blood count
) done to rule out any bleeding tendencies.
