Ask an Eye Doctor and Get an Answer ASAP
This is Dr. David
I am sorry about what your younger brother is going through.
I would be scared as well if he cold me the same things.
Complete anhedonia is the loss of feelings and emotions and can occur in patients who suffer from depression or other mental issues.
the pressure behind his eyes could be due to headaches, dehydration, sinus inflammation, sinus infection, allergies or other causes.
he is at an age where he should be seeing a primary care doctor and talking to them about his symptoms
he may benefit from seeing a psychiatrist and starting possible psychiatric medications.
I hope he is willing to see a doctor about his symptoms.
