I have to wonder if this teen just suffered from severe migraines which were caused by something else and possibly even genetic. I have suffered with migraines all my life and they started around my high school years. They would come and go and NO normal pain relief ever worked like Aspirin or Advil. They typically last many hours and usually start in afternoon and once they start they last most of the day if not all day long. Very Very Very painful and depressing. Loud sounds and light were intolerable once the migraine set in.
Its amazing I was able to suffer through them so many years. What helped me was I would sometimes have months where they would not surface and that helped.
I went to MANY doctors over the years and nothing really worked until I finally and very luckily went to a Neurologist in my 30s. He finally correctly diagnosed me that I was suffering from real migraines and prescribed a simple but very new medicine that totally knocks it out whenever I get a migraine.
He told me that my genetic capillaries (blood vessels) were most likely too small and thin than most people in certain parts of my brain which constricts the blood flow to areas where it should not be restricted. Or something like that LOL
He said some people just get these types of migraines and others don't. I frankly didn't care what the cause was since he found a medicine that works wonders. I now carry it around ever since and I just take 1 whenever I get the migraine type headache. And POOF totally gone within 1/2 hour.
I get normal headaches on occasion too and Advil typically knocks it out. Migraines are a whole different other animal and I have found certain triggers that seem to make them come on but other times they just come on by themselves.
I wonder if this girl had something like I had and the parents was just blaming it on WIFI because they could not figure it out like me.
I really wish that poor girl could have went to my doctor and got some medicine that may have cured her symptoms. It took me many years before I found the right kind of help. I suspect they were in that situation. A LOT of doctors did not know how to treat me until I finally met 1 who did.
And even if she was truly sensitive to WIFI signals the fancy new medicines they have these days could have possibly helped relieve her symptoms. I don't know how many doctors they tried but I had to go through MANY different doctors over MANY years before I found one that helped me. It does get frustrating and you do want to give up trying different doctors but that is all you can do. I have to wonder if the right doctor could have helped her.
