My 81 yr old sister had a bad trauma last week. She told me she had a terrible headache one early morning. This is the first time this happen to her. She was able to drive herself to the emergency hospital and saw a physician.She had her head scan and found negative. She was told to see an specialist the next day for further consultation. Her veins on both sides of her temple was popped out and plus headache . She was given a biopsy on both sides of her temple. She is feeling fine now but be back Monday for follow up of the results. She is very scared of the results. Overall, her health is just fine except she had a cataract surgery(both eyes) recently.She remember one doctor says that it may cause blindness. Please advise. Thank you.Concern brother
