Hi Crimson Butterfly,
I agree with Ann, your boyfriend should see a doctor to rule out anything serious.
However, if it makes you feel better, I have had migraines with these symptoms. I have often felt so sick that I'm sure I have a tumour because I lose sight in my eye, experience confusion and many other strange symptoms that go away with the migraine. It is simply the swelling of a blood vessel putting pressure on part (or parts) of the brain that aren't able to function.
As a rule, whenever anything happens for the first time that is concerning, it's a good idea to see the doctor. As a migraine sufferer I have had many strange firsts and have found that even though I feel like I have a tumour or am having a stroke, it's just a migraine.
I hope this helps reassure you a little bit. My thoughts and prayers are with you and your boyfriend.
I cannot always control what goes on outside. But I can always control what goes on inside.
