Hi and welcome

Did the doctors check for any type of vitamin deficiencies? They can check this with blood work.
Does your friend have allergies? Is his work environment clean, are there any chemicals he is exposed to?

He should not have to deal with this, no one should deal with any discomfort. I get frustrated when I hear this. You are a caring friend to be looking for answers..

If they found sinusitis...it should have shown up in his MRI as well? I was misdiagnosed for YEARS with sinusitis and then I went to an ENT and he told me that if you have sinus problems extensive enough to bring you to him/her that they should show up SOMEWHERE/SOMEHOW on the MRI? So I would look further into that...

Also if the headaches are daily...I just found out that I was suffering from something called Transformed Migraines. Daily Migraines that tend to worsen in your 20s or 30s...so it's worth it to talk to him about it and research it. I found out a lot on my own just researching on the internet in order to have a "knowledge base" to ask my Neurologist questions. There is absolutely no need for him to suffer like that if something can be done so props to you for trying!!!!!

You're a wonderful friend. He is lucky to have you! Let me know if I can help at all.

Best of Luck!

I have had the same thing! for the past 3.5 years. It started as a Sinus Infection which they tell me was cured but the headache stayed exactly the same. I am still looking for a cure now. I have seen around 10 doctors, tried migraine meds, accupuncture, physical therapy, had 3 MRI's and 2 CT scans, and even had neck injections. Nothing has made any difference. Painkillers don't really erradicate the pain completely either. email me his contact info. Was he ever cured of this? I would give anything for this to go away.

I wish I had a friend like you too, all my friends, even my parents either don't know or don't care and don't do anything further than that. I've had the same for 6 years, although my sinus infection may not have been successfully treated yet, I have a feeling my headaches will probably stay too. Any solutions will be duly noted!
