Grandson, 21 yr old college student feeling not right in his head, headache in one spot at back of neck, loss of weight, no appetite, soreness of muscles , thirsty, all blood work was normal this past week. Had first panic attack a few days ago.Says looking at certain patterns, sometimes tv or computer, he gets a funny feeling. He is worrying about feeling "spacey" all the time and not being "sick". He is not a complainer. Just had an ultrasound of a movable fatty feeling lump under his arm that he has had for a year and never told anyone. Don't have results back from that yet . What would be your thoughts? Thanks
