Hi everyone,
I’m 19(f)
I just need advice back in January I did my medical and with that a question was asked about headache and migraines I was unsure what to say or what no too as it was my first time I told the medical person that I have light headache they don’t come often it’s nothing serious she flagged it up and i became TMU for four months I’ve been chasing my gp because I’ve never been diagnosed with a headache or migraine nor do I have treatment for it gp sent my record and I even got a letter from my gp saying that I do not suffer from any headache migraine or period issue I just got an email saying I’m PMU? I’m absolutely confused could I appeal? Because I got rejected for no reason at all?
