Hi There My Partner Has Been Having A Few Health

Hi there my partner has been having a few health issues lately, he has hemacromatosis also he has tinasis. He goes every three months to get his blood taken off for his hemacromatosis he was feeling realy sick for awhile extreme tiredness and fatigue he says he feels like there's nothing in his body, also he's been having really bad headaches every day and panadol just doesn't make a dent in his headache he's also been complaining of pain in his legs he rated it an 8/10 pain wise. So he went to get his blood taken off early but it's made no diffrence he still feels horrible and it effects everything he does!!! He's been to the doctor but as usual they were not very helpful said to come back in a month ?!!? I surgested he could be low in vitamin b12? But of course he can only have vitamins that don't have iron in them due to his blood having such an extreme iron count. please help!! Thanks
