Temples injected with HA filler, needle just below the skin. First time. During left temple, sudden urgent pressing, Dr. abruptly left, returned after 20sec, more pressing. Vision in the left eye was much dimmer than the right. I could feel a 'ball' of filler. I asked if ok. Dr. reply, 'Yes, it's just…'. No real answer. More pressing, then, all seems ok. No bruising, and healed fine. Was there a problem during injection? Maybe I have an anatomical anomaly and should stop filling temples?
