My son, who is a 33 year old, black male, just called me stating he has been experiencing dizziness, lightheadedness, clogged ears and pain in his facial jaw for several weeks. Saw a doctor today, was assessed, had a CT scan but stated he could not find anything wrong. He is a vegan, does not smoke (anything) or drink alcohol. Don t know if this is important or not but he and his wife are art teachers in Shenzhen, China. Also, other than being his mother I am a nurse. please advise. I looked up the symptoms and saw numerous things it could be, but not being there with him as well as not being a doctor, we need advice.
